Berkeley, Calif. (October 4, 2023) – Bolt Threads, Inc. (“Bolt Threads”), a pioneer in sustainable biomaterials for consumer products, announced a definitive agreement for a business combination with Golden Arrow Merger Corp (Nasdaq: GAMC) (“Golden Arrow”) that would result in Bolt Threads becoming a public company. Upon closing of the transaction, the combined company will be named “Bolt Projects Holdings, Inc.” and is expected to remain listed on Nasdaq under a new ticker symbol “BSLK”. Bolt Threads Founder and CEO Dan Widmaier will lead the combined company.


Company Overview


Bolt Threads is a mission-driven biomaterials platform created to enable a better future for people and the planet. It applies biotechnology to innovate new solutions and products to help transform consumer goods. With 13 years of research, testing, and developing innovative materials inspired by natural biodiversity, Bolt Threads aims to replace the status quo of ingredients and processes found in the manufacturing of high-volume consumer goods with sustainable alternatives from nature. Bolt Threads’ intellectual property portfolio is anchored by 49 granted patents and 171 pending patent applications.


Bolt Threads’ lead product, b-silk™, is a fully biodegradable, non-toxic, and versatile ingredient for the beauty and personal care industry that benefits consumers, formulators, and the environment. It has been in the market since 2020 and is in products found in Sephora stores throughout the U.S.


The beauty industry relies on silicone elastomers in a vast array of formulations, a synthetic ingredient that leaves biopersistent polymers, including microplastics in the water system and is coming under increased consumer and regulatory pressure. Until Bolt Threads introduced b-silk, there have been few suitable alternatives to date. The proprietary polypeptide in b-silk replaces silicone elastomers in a broad range of formulations while offering added active benefits to skin, hair, and color cosmetics. B-silk’s novel protein polymer is inspired by the same proteins found in spider webs and is biobased and biodegradable.





Bolt Threads Investment Highlights


Up to $4.0B silicone elastomer market within the $20B silicone-based ingredients and the $371B global beauty & personal care markets
Differentiated patent-protected product, offering a highly compelling value proposition
A deep bench of branded customer relationships, enabling rapid product iteration and commercialization
Potential for an attractive financial profile through scale and innovation
Numerous growth opportunities for new molecules and materials from nature to meet customer and consumer needs
An experienced and multi-faceted leadership team


“Our mission remains steadfast to develop and provide better solutions for a way better world, and we believe that going public will allow us to grow our biomaterials platform and bring b-silk, among other products, to commercialization faster. Bringing low impact innovative materials to market is increasingly difficult and desperately needed,” said Dan Widmaier, Bolt Threads co-founder and chief executive officer. “This is a transformative partnership and deal with Golden Arrow and its sponsor, which incorporates four firms with several decades of experience in capital markets and investing in public and private companies, who are also investing up to $10M, consisting of up to $8M in our PIPE transaction and $2M in an interim bridge financing.”


“We were impressed by Bolt Threads’ proprietary technologies and processes that are on the cusp of enabling the company to become a leading platform for sustainable materials development,” said Jacob W. Doft, Chairman of the Board at Golden Arrow. “We see a significant investment opportunity in the innovation and commercialization of biomaterials in industries ripe for disruption. We believe Bolt Threads, with its strong brand and reputation with customers, is well positioned to execute on its high growth strategy with market-ready products that will overhaul industries beginning with beauty and personal care.”


Transaction Overview


Golden Arrow has agreed to combine with Bolt Threads based on a $346.1M pro forma enterprise valuation.

The financing is anchored by existing Bolt Threads’ stockholders that include Baillie Gifford, Temasek, Top Tier, Founders Fund, Formation 8, and Foundation Capital, and a total investment of up to $10M from the Golden Arrow sponsor (subject to reduction to the extent certain existing Golden Arrow public stockholders elect not to redeem in connection with the transaction).
