Sanmina was founded by Jure Sola and Milan Mandarić in 1980 as a manufacturer of printed circuit boards. It later expanded into manufacturing backplanes and backplane subassemblies. By 1989 the company's revenue had grown to around $60 million and it was focused on providing electronics manufacturing services for several customers in the telecommunications industry. That year, Sola led a management buy-out of his co-founder's share in the company with investment from Morgan Stanley and became its president.
Initial growth: 1990s
In 1991, Sola became Sanmina's chairman and CEO. In the 1990s original equipment manufacturers (OEMs) had increasingly begun outsourcing production to firms like Sanmina. Sola was able to grow the company in the early 1990s by focusing on providing contract manufacturing, and Sanmina established itself as an electronics manufacturer for OEMs. The company increased its annual revenue by more than $20 million over the 5 years following the management buy-out. In February 1993, the company went public.
Through the 1990s the company expanded its operations in the US and internationally through acquisitions of electronics manufacturers and manufacturing services companies. Between 1993 and 2000, Sanmina bought manufacturing assets from Golden Eagle Systems and Lucent Technologies, acquired Comptronix, Pragmatech, Hadco and Altron and merged with Elexys International.
In 1997, the company was ranked the ninth largest contract manufacturer. It had taken advantage of the growth in telecommunications in the 1990s by focusing on providing manufacturing services for customers from that industry. Sanmina focused on manufacturing products that were harder for client companies to make themselves, such as components for premium networking and telecommunications applications. By 2000, the company had expanded into manufacturing for the mobile communications, high-tech, and medical instrumentation industries. In 2001, manufacturing for telecommunications clients made up 70 percent of the company's revenue.
By April 2001, the company had around 20,000 employees and operated 75 facilities in 13 countries. In 2001 the company was affected by the downturn in the technology industry. Sanmina's sales decreased by 20% in early 2001 and it made layoffs and closed some US facilities, however its revenue continued to increase, which was credited to the company's focus on higher margin products for the telecommunications industry.
Global expansion: 2000s
In 2001, the company acquired and merged with SCI Systems, a larger competitor with operations in the US and Europe. SCI was founded in 1961 as Space-Craft Inc. and became a supplier to the defense and aerospace industries before diversifying into contract manufacturing for private companies. At the time of the merger, SCI manufactured a broader range of products compared with Sanmina, including a focus on assembling personal computers (PCs). Although SCI was the larger company with higher revenues, Sanmina had a higher market valuation, which allowed it to buy SCI. The companies completed the merger in December 2001, establishing Sanmina-SCI Corporation as the resulting combined company. The acquisition of SCI was the largest acquisition in the electronics manufacturing services industry to that date and made Sanmina-SCI the joint second-largest EMS company.
After the merger, the company restructured and broadened its customers to be spread over a wider range of markets by the mid-2000s. In the early and mid-2000s Sanmina-SCI, the company closed some US facilities and expanded its international operations in Asia as it moved some manufacturing abroad. The ongoing downturn in the technology industry, and the company's post-merger reliance on the lower-margin PC manufacturing business affected the business. The company sought to reduce costs by moving manufacturing to countries with lower cost of labor. In 2008, Sanmina-SCI decided to exit the PC manufacturing business citing its low margins. The company sold its PC manufacturing operations to Foxconn and a manufacturing plant in Mexico to Lenovo. After the sale of the PC business, Sanmina-SCI focused on developing strong relationships with OEMs as well as drawing from SCI's experience with defense contracts to focus on the defense industry. As of the late 2000s, the company's defense and aerospace operations were headquartered in the Huntsville, Alabama area, where it manufactured technologies such as battlefield communications systems for clients including Boeing and General Dynamics.
On November 15, 2012, the company changed its name to Sanmina, dropping SCI from its name.
On July 2, 2015, the company announced that it had acquired the CertainSource Technology Group.[citation needed]
Change of leadership
Bob Eulau replaced co-founder Jure Sola becoming the CEO effective October 2, 2017. After this change, Sola assumed the role of Executive Chairman of the Board . Hartmut Liebel assumed the role of CEO in October, 2019. Jure Sola returned again as CEO in August 2020.
On May 11, 2018, Ather Energy, announced it had entered into an agreement with the company to develop and manufacture key components for its maiden scooter and production would take place in the company's facility in Chennai, India.
On March 3, 2021, Astrotech Corporation announced that its Astrotech Technologies, Inc. subsidiary has entered into an agreement with Sanmina Corporation to manufacture its mass spectrometry products. As part of the relationship, Sanmina will manufacture 1st Detect’s TRACER 1000. They have also agreed to manufacture AgLAB’s AgLAB-1000 and BreathTech’s BreathTest-1000 once those products are officially released.[citation needed]
On October 27, 2025, Sanmina announced the acquisition of ZT Systems, a leading provider of data center infrastructure and manufacturing solutions, from its previous owner, AMD. The transaction was valued at approximately $2.55 billion in a combination of cash and equity, with the potential for up to an additional $450 million in performance-based earnout bonuses subject to achieving specific financial and operational milestones. Strategic rationale for the acquisition centered on expanding Sanmina's footprint within AI and Cloud manufacturing services, enhancing high-density server integration, and deepening its comprehensive end-to-end global manufacturing capabilities for enterprise and hyperscale data center clients.
Lawsuits
In 2023, it became known that Sanmina was engaged in ongoing litigation with its former partner, Dialight, concerning the termination of their manufacturing services agreement.
In 2024, the claims against Sanmina for fraudulent inducement proceeded to trial after a New York court rejected Sanmina’s bid to dismiss Dialight’s fraud allegations.
