W. L. Gore & Associates Submits IPO Prospectus After 65 Years as a Private Innovator in ePTFE Medical Implants

On January 1, 1958, founders Wilbert L. “Bill” and Genevieve “Vieve” Gore established in the basement of their home in Newark, Delaware,W. L. Gore & Associates, Inc.(hereinafter referred to as GORE).

This is a company that initially served the electronics market, with its product solutions centered on polytetrafluoroethylene (PTFE).It was not until 1969 that Bill and Vieve’s son, Bob Gore, discovered a new polymer—expanded polytetrafluoroethylene (ePTFE).This polymer expanded the application scenarios of PTFE, and W.L. Gore & Associates’ product portfolio began to diversify, includingMedical implants, fabrics, cables, filtration materials, ventilation equipment, sealants, membranes, and fibersproducts, among others, have been developed and brought to market.

Key Milestones in the Development History of W. L. Gore & Associates, Inc.

After more than 60 years of development, GORE’s business has expanded into aerospace, medical technology, biopharmaceuticals, cable assemblies, plant fibers, electrochemistry, semiconductors, automotive, and music. The company holds over 3,400 proprietary inventions and more than 5,500 patented technologies worldwide, the vast majority of which stem from the development of ePTFE materials.

Expanded polytetrafluoroethylene (ePTFE) is the core material in many of GORE’s products.. When PTFE is expanded, an ePTFE membrane is formed, creating a microporous structure with desirable properties, including a high strength-to-weight ratio, biocompatibility, and high thermal resistance.

GORE can customize ePTFE according to the desired application and function.，Enabling it to have different structures based on the application: for example, high or low density, tight or open porosity, thinness or thickness, surface or cross-sectional orientation, and various geometric shapes and asymmetries,thereby forming a variety of product forms, including tapes, films, tubes, fibers, or rods. EngineerFurthermore, modify the geometry of the original fiber connection nodes based on the product's application scenarios to further optimize the required performance.。

Since the discovery of ePTFE in 1969, leveraging expertise in materials science and a deep understanding of application requirements, it has been used in medical devices implanted in the human body, mountaineering suits for Everest expeditions, and electronic cables transmitting signals from outer space.GORE consistently upholds its development philosophy of “Innovating Technology to Improve Lives.”。

With the commercialization of the first GORE-TEX® implant in 1975, W.L. Gore & Associates officially entered the commercial market in the medical field.。GORE leverages the excellent properties of ePTFEBiocompatibility、Chemical InertnessandAntibacterial Capability, expanding its product pipeline over the past nearly 50 years toVascular Graft、Endovascular Interventional Devices、Prosthetic Stent、Biosynthetic Tissue Patch、Sutures and Suture Reinforcement Materialsetc. To date, W.L. Gore & Associates has provided products to departments including cardiovascular surgery, thoracic surgery, general surgery, gastroenterology, stomatology, and pediatrics worldwideNearly 50 Million Medical Implants, becoming a global leader in the field of biomaterials.

Vascular grafts, as one of the main product lines of W.L. Gore & Associates,Four main product categories are sold in the Asia-Pacific region: GORE-TEX^®Vascular Graft, GORE-TEX^®Stretching Vascular Grafts, GORE-INTERING^®Vascular Graft^®and GORE-PROPATEN^®Vascular Graft^®。

GORE-TEX^®The vascular graft is a first-generation ePTFE vascular graft,Primarily used to improve outcomes in peripheral, aortic, and vascular access surgeries。

This series of vascular grafts is made from GORE-TEX^®added to the vascular graft"Functions of Stretching", the “stretching”-inducedLongitudinal compliance enables the graft to better match the mechanical properties of native vessels., therebyReducing Thrombosis and Stenosis Associated with Transplantation. In addition to a wide range of size specifications, W.L. Gore & Associates has also designed this product series intoBifurcated, Renal Dialysis Vascular Access, and Pediatric-Specific Types. Among them,Pediatric-specific vascular grafts enable successful palliation in neonates with cyanotic congenital heart defects prior to definitive repair.

The third category of ePTFE vascular grafts, GORE-INTERING®, combines the advantages of ringed and non-ringed grafts for more delicate vascular surgeries. This productMade of reinforced ePTFE, while maintaining the same inner lumen diameter, reducing the outer profile to 76% of that of other vascular grafts,It is currently the vascular graft with the smallest outer profile and radial support.. Recommended for procedures such as lower extremity bypass and above-knee or below-knee reconstruction.

Addressing thrombosis on the luminal surface of vascular grafts is a challenge faced by all vascular surgeons, GORE-PROPATEN^®Vascular Graft^®is specifically designed for vascular surgeries at risk of acute graft thrombotic failure.

GORE combines the anticoagulant function of heparin molecules with the graftability of ePTFE material to develop the CBAS heparin surface with durable anticoagulant properties.

CBAS Heparin Surface Structure

The terminal ends of heparin molecules are covalently bonded to the ePTFE surface., keeping the active sites of heparin constantly exposed to the environment.The active site of heparin can bind to antithrombin., antithrombin undergoes a conformational change to bind thrombin and form a complex, andDetachment from the surface of heparin molecules, thereby completing the anticoagulation process.

Mechanism of Anticoagulant Action of Heparin-Coated CBAS Surfaces

In preclinical in vivo studies, the GORE-PROPATEN® Vascular Graft demonstratedSuperior Antithrombogenicity and Patency. In canine aorto-iliac bypass trials, no thrombus formed on the luminal surface of the vascular graft after two hours. In actual clinical practice, among cases where grafts were explanted at 3, 4, and 8 years,"The detected heparin activity level was higher than the heparin activity level required for anticoagulation as verified in rigorous blood-contact tests, and no mural thrombus was formed."

Canine Aortoiliac Bypass Trial

GORE was named one of Fortune’s 100 Best Companies to Work For® for Millennials™ in 2021, andRanked by Forbes as one of America’s 200 largest private companies. The company nowAnnual revenue has exceeded $3.8 billion(Data fromGore Stories | History and Information | Gore (gore.com)), but founder Bill Gore wanted to build a truly fully democratic and innovative company, so it has not gone public to date,GORE remains a private company.。

Nevertheless, this has not hindered the development and progress of W.L. Gore & Associates. The company adopts a prudent approach to recruiting new talent and offers training programs and scholarships to cultivate and inspire employees, enabling them to maintain their innovative capabilities while exercising caution toward the future. Meanwhile, while remaining a technology-driven enterprise, the company continues to achieve breakthroughs in exploring new frontiers, advancing its global commercial layout, and expanding its AI technologies.

At W.L. Gore & Associates, there are sponsors and leaders, not bosses.Founder Bill Gore believed: “Dictators cannot impose commitment; they can only impose orders.”Therefore, at GORE,Individuals do not require close supervision; the company inspires their work enthusiasm, guides and supports them in making commitments to the team, and holds them accountable for fulfilling those commitments.

Each new employee will be assigned a sponsor/supporter., and help him find a good fit between his skills and the specific needs of various teams. Sponsors/supporters make a personal commitment to employees’ development and success. As the organization has evolved, the sponsor/supporter team has begun holding annual meetings to gain a broader understanding of employees’ potential under their guidance. Employees are also free to seek new sponsors/supporters if they wish.

Sponsors and supporters at W.L. Gore & Associates cultivate influence and “natural leadership” among employees by establishing track records and fostering team cohesion. This distinctive corporate management model now extends to nearly 12,000 GORE employees across more than 30 countries and regions worldwide.

In the future, W.L. Gore & Associates will continue to operate as a privately held company, with a focus on employees’ personal growth and independent innovation, ensuring that the company consistently evaluates business value through a long-term lens.
