Zetwerk Pvt., an Indian contract manufacturer, is preparing to publicly file for an initial public offering that could raise as much as $400 million, according to people familiar with the matter. The company has received preliminary approval from India's Securities and Exchange Board and is eyeing a September launch pending updated regulator feedback.

The $400 million target equals 4,200 crore rupees and values the company at approximately $4 billion, according to the company's submission to SEBI in July 2026. Zetwerk received formal approval from the regulator on July 9, clearing the way for the public filing phase. The timeline compresses the typical IPO preparation window; most Indian industrial companies spend four to six months between SEBI approval and market launch.

Zetwerk operates as a contract manufacturer serving sectors including automotive, aerospace, industrial equipment and consumer goods. The company manages operations across multiple Indian states and counts institutional investors including Accel Partners, Norwest Venture Partners and Lightspeed Venture Partners among its backers. Prior funding rounds valued the company at lower multiples; the IPO represents a significant step-up in valuation for a company founded in 2011.

The manufacturing sector in India has drawn increased capital toward automation and precision production in recent years. Zetwerk competes with established contract manufacturers and smaller regional players, though few Indian peers have pursued public markets in the past three years. The IPO would be one of India's larger industrial offerings in 2026 by target size.

September timing would require Zetwerk to complete its draft red herring prospectus and respond to any SEBI queries within the next three to four weeks. The company has not yet announced a final offer size, price range or listing venue, though NSE and BSE are the typical venues for Indian equity offerings of this scale.

If Zetwerk launches in September as targeted, the IPO would arrive during a period of moderate retail and institutional appetite for Indian industrial stocks. The company's ability to hit the timeline depends on regulatory turnaround speed and management bandwidth to complete prospectus filings and roadshow preparation in parallel.
