Capital Allocation Strategy To reach proﬁtability Bolt Threads intends to invest in three primary areas: 1. Market Penetration : growing the customer base and number of SKUs in which b - silk Œ appears 2. Expand supply of b - silk Œ : bring on additional Contract Manufacturing Organizations [CMOs] for expanded capacity and business continuity of supply 3. Cost of Goods Sold [COGS] Optimization: iterative reﬁnement of the production process in each manufacturing campaign to continue improving COGS for b - silk Œ and expanding gross margins Bolt Threads is currently focused on the commercialization of the most market mature and low capital requirement products in their portfolio. B - silk Œ is a proprietary compound produced on our behalf by contract manufacturing organizations (CMOs). Driving costs lower in this process is a matter of scale, operating improvements, process improvements and continued work on strain and protein engineering with strategic partner Ginkgo Bioworks . From a ﬁnancial standpoint, in order to manufacture b - silk Œ , Bolt Threads requires a modest operating investment to bring online commercial infrastructure, NEGLIGIBLE capital investment, and minimal cash in inventory because of a make - to - order model.

Market Opportunity Assessment 04

Fleeting CONSUMER Benefit Silicone elastomers provide status quo beneﬁts to consumers, offering the temporary illusion of smoothness and moisture, but the effect vanishes when washed off skin and hair. The beauty industry relies upon silicone elastomers in a vast array of formulations. This synthetic ingredient leaves microplastics in our water system and is coming under intense regulatory pressure . Manufacturers HAVE LONG BEEN searching for BETTER alternatives, but to date there have been FEW suitable substituteS. THE INDUSTRY Problem: Market Opportunity Assessment — 25

Silicones are synthetic ingredients that come in the form of oils and gels with a more or less thick texture. “ What are silicones? To identify them in our products, take a look at the ingredients list on packaging. They can be found under names such as: DIMETHICONE PHENYL TRIMETHICONE CYCLOPENTASILOXANE AMODIMETHICONE DIMETHICONOL CYCLOMETHICONE. The easiest way to identify silicones is to look for words that end in one of these: – cone, – conol, – silane or – siloxane.” Silicones are used in some cosmetic products thanks to their unique sensory beneﬁts and properties, as long lasting effect in lipstick . Silicones are smoothing : they give products like creams or make - up a silky, spreadable, luxurious texture . They also give shine and softness in shampoo and other hair care products . ” “ What are they used for? Silicones are accused of build - up effect on skin and hair . The sensorial feels are also discussed : a quick hair lubrication and a non - soft touch on skin . Silicones are not easily biodegradable in the environment, meaning some silicones accumulate . The silicone called cyclotetrasiloxane (D 4 ) is suspected of having carcinogenic, mutagenic or toxic effects for reproduction . This ingredient is forbidden by European Regulation . ” “ Why are they questioned? Industry LeaderS disclose EXTENSIVE USE OF silicones DESPITE QUESTIONABLE IMPACT Source: L’Oreal, Inside Our Products [1] * * See Appendix for additional source information Market Opportunity Assessment — 27

THE SHIFT AWAY FROM SILICONES IS DUE TO A Combination of regulatory Pressure, Consumer FEEDBACK, & Brand Ethos GROWING REGULATORY PRESSURE The European Union restricts D 4 and D 5 to 0 . 1 % or less in wash - off personal care products in 2020 . It is expected to add D 6 to that restriction and extend it to leave - on products and other consumer goods as soon as this summer . The European Chemicals Agency lists D 4 , D 5 , and D 6 as persistent, bioaccumulative, and toxic . All linear silicones are also under review due to their environmental impact and expected to be regulated by 2028 - 2030 . Neslihan Utkan , who leads the Americas personal and home care division of the chemical maker Clariant , says the EU restrictions are driving consumer product makers to reformulate without silicones . She says her customers expect the bans to spread both in scope and geography, and they want to be ready . They also prefer to have one formulation they can sell around the world . Source: Chemical & Engineering News, May 2023 [2] GROWING Consumer FEEDBACK Despite the industry effort to defend silicones, consumers search for silicone - free formulas for ten common reasons : 1. Silicone clogs your pores 2. Silicone blocks other ingredients from absorbing into the skin 3. Silicone can cause breakouts, irritations, and acne 4. It does not support skin health 5. Silicone can dehydrate your skin 6. Silicone slows down cell turnover 7. Silicone is difficult to remove from the skin 8. Silicone is bad for the environment 9. Silicone can accelerate aging 10. Silicone is a chemical and is not natural Source: Fitﬂow Beauty, July 2019 [3] BRAND ETHOS & ESG COMMITMENTS Beauty brands’ main growth drivers are innovation and brand ethos . Consumers align purchases to three things : product efficacy, brand ethos, and brand Environmental, Social, and Governance (ESG) efforts . Brand leaders aren’t afraid to speak to silicone’s lack of performance beneﬁts coupled with environmental drawbacks : “Silicones, despite having delightful mechanical properties as ﬁlm formers and waterprooﬁng agents, don’t belong in beauty or personal care products . They are bioaccumulative substances, meaning they build up in the ecosystem and often end up in the tissues of the living beings within that ecosystem . They aren’t known to be very good for your skin either . ” — BRETT BILLON Co - Founder, Plume Cosmetics Source: Beauty Heros, May 2023 [4] Market Opportunity Assessment — 28

Industry Leaders NOTE CONSIDERABLE CHALLENGES WITH CURRENT SILICONE - FREE ALTERNATIVES FOR NATURAL FORMULATIONS Source: Chemical & Engineering News May 2023 [5] “ The chemical distribu tor Univar Solutions has both silicones and silicone replacements . “If a c ustomer is interested in a speciﬁc skin feel and they are not averse to using silicones, that’s probably the best option,” says Arnita Wofford , Univar’s Global Marketing And Technical Director for beauty and personal care . “The customer who comes in and says, ‘I want this long - wear, waterproof eyeliner, but I want it to be 100 % natural,’ well, let’s take a step back . If you’re not willing to use any synthetic ingredients, you will not achieve that goal . So it’s also our job to keep them honest and manage their expectations . ” “ BASF , which doesn’t make silicones, has been working on alternatives for more than a decade, says Joel Basilan , the ﬁrm’s head of Application Technology For Personal Care in North America . “We know that this is a trending need, so we continue to innovate in this area . ” “ Diane Dabkowski , a chemist and R&D manager at Avon says the company has evaluated the replacement offerings fro m numerous suppliers . In general - purpose lotions and products in which silicone is a minor ingredient, the replacements are OK, she says, but not when the silicone is part of the backbone of the formula . “The key thing that really got people looking at silicone is lack of biodegradability” — Neil Burns, P20 Science “ Isabel Almiro do Vale , Global Marketing And Strategy Directo r For Personal Care at Dow , says the industry focus on biodegradability puts silicones at an unfair disadvantage because their degradation mechanisms aren’t biological .

INDUSTRY GIANT UNILEVER SPEARHEADS A COMMITMENT TO BIODEGRADABILITY Source: Unilever, May 2021 [6] “ Through our Safety and Environmental Assurance Centre (SEAC) team, we have always assessed our ingredients to ensure e n vironmenta l safety, but we kno w that consumers want even more reassurance . “ For every product that currently includes non - biodegradable materials, we will either remove the ingredient and replace it with a similar biodegradable alternative or reformulate the product . ” — Ian Malcomber, Unilever SEAC’s Chemical Safety Programme Director “ By 2030, all the ingredients we use in our products will biodegrade completely & quickly. ” When people use home, beauty and personal care products – from shampoos and body washes to laundry detergents and washing - up liquids – they end up going down the drain . That’s unavoidable – it’s simply how they function, to do what they do . But we want to make sure that, in doing so, our products are kind to the planet . Market Opportunity Assessment — 30 “

Silicones are mainly used in: Hair Care Products: Silicones, especially dimethicone, are commonly found in shampoos, conditioners, and hair serums. They give a smooth and shiny ﬁnish to the hair, help in detangling, and protect hair from heat damage. As consumers continue to invest in haircare and styling products, the demand for silicones is expected to grow. Skin Care : Silicones like cyclomethicone and dimethicone are used in skincare formulations for their smoothing properties . They help in providing a silky texture to products, making them spread easily on the skin . This is especially valuable in products like moisturizers, sunscreens, and primers . Makeup: Silicones play a vital role in the formulation of makeup products, including foundations, primers, mascaras, and more. They help in providing longevity, water resistance, and a smooth application. Anti - Aging Products: Silicones can assist in ﬁlling ﬁne lines and giving a plump appearance to the skin, making them a popular choice for anti - aging formulations. Deodorants and Antiperspirants: Silicones help in improving the texture of these products and can aid in providing a smooth glide during application.

RISK FACTORS Risk Factors — 59 All references below to “Bolt,” the “Company,” “we,” “us” or “our” refer to the business of Bolt Threads, Inc . The risks presented below are certain of the general risks related to the business of the Company and the Business Combination, and such list is not exhaustive . The list below is qualiﬁed in its entirety by disclosures contained in future documents ﬁled or furnished by the Company and Golden Arrow Merger Corp . (“Golden Arrow”), with the U . S . Securities and Exchange Commission (“SEC”), including the documents ﬁled or furnished in connection with the proposed transactions between the Company and Golden Arrow . The risks presented in such ﬁlings will be consistent with those that would be required for a public company in its SEC ﬁlings, including with respect to the business and securities of the Company and Golden Arrow and the proposed transactions between the Company and Golden Arrow, and may differ signiﬁcantly from and be more extensive than those presented below . Risks Related to Bolt’s Financial Position 1. Bolt Threads has a history of net losses and its ability to achieve or maintain proﬁtability in the future is uncertain. 2. Bolt’s operating results may ﬂuctuate signiﬁcantly as a result of a variety of factors, including, but not limited to, end market demand, timing of regulatory actions and variation in manufacturing costs, many of which are outside of its control. 3. Bolt will incur signiﬁcant expenses and capital expenditures in the future to execute its business plan and it may be unable to adequately control its expenses or raise additional capital on favorable terms, if at all. 4. Bolt may not be able to generate sufficient cash to service all of its debt and operating lease obligations, and may be forced to take other actions to satisfy its obligations under its debt and operating lease obligations, which may not be successful. 5. Despite its current signiﬁcant indebtedness, Bolt may be able to incur more debt in the future, which could further exacerbate the risks of leverage, including the ability to service its indebtedness. 6. A limited number of customers, distributors and collaboration partners account for a material portion of Bolt’s revenues. The loss of major customers, distributors or collaboration partners could harm Bolt’s operating results. 7. Bolt is subject to a number of restrictive debt covenants under its loan agreements. 8. Bolt’s ability to use net operating losses to offset future taxable income will be subject to certain limitations as a result of the Business Combination and related transactions. Risks Related to Bolt’s Products and Operations 9. Bolt’s b - silk Œ and future product candidates may not achieve market success. If Bolt’s products do not achieve market success, it may be unable to generate signiﬁcant revenues. 10. Bolt may be unable to manage rapid growth effectively, and its ability to successfully implement its business plan will depend on a number of factors outside of its control. 11. B - silk Œ pricing and availability may be impacted by factors out of Bolt’s control, including, but not limited to, end market demand, variation in manufacturing costs, and supplier availability. 12. If Bolt's manufacturing costs materially increase, Bolt would have to raise its prices, which could negatively impact its ability to gain new customers and keep existing customers. 13. Bolt has limited experience in marketing and selling b - silk Œ , and if it is unable to gain market acceptance from consumer product companies and others, its business may be adversely affected. 14. The loss of one or more of Bolt’s signiﬁcant customers, a signiﬁcant reduction in their orders, their inability to perform under their contracts, or a signiﬁcant deterioration in their ﬁnancial condition could have a material adverse effect on its business, results of operations, and ﬁnancial condition. 15. Bolt's estimated contracted revenue vary from purchase orders on an “as needed” basis to contracts with minimum purchase obligations, and the failure of Bolt's customers to continue placing orders or to abide by their contracts could have a material adverse effect on Bolt's operations and ﬁnancial results. 16. Bolt currently relies on a single manufacturing facility for all of its manufacturing needs and in the future intends to rely on a small number of manufacturing facilities both in the U.S. and internationally. 17. If Bolt is unable to ensure the safety of its products or if consumers perceive its products as unsafe, its business may be adversely affected. 18. Bolt has limited experience in producing large quantities of b - silk Œ and may not be able to cost - effectively produce b - silk Œ sufficient to meet customer demand in a timely or economical manner. 19. Bolt may face challenges producing its products at commercial scale and at commercially viable cost, and it may not be able to commercialize its products to the extent necessary to make a proﬁt or sustain and grow its current business. 20. B - silk Œ is manufactured in part through fermentation equipment owned by a number of different suppliers. If Bolt is unable to maintain adequate fermentation capacity with its suppliers or increase fermentation capacity as it grows, it may be unable to produce a sufficient amount of b - silk Œ . 21. Certain contracts granting exclusivity rights to customers may limit Bolt’s ability to sell products in certain markets. 22. Bolt may face, substantial competition from incumbent materials as well as other new entrants, and if Bolt is unable to continue developing innovative products and technologies and/or scale its production, Bolt may fail to gain, or may lose, market share to its competitors. 23. If Bolt is not able to successfully commence, scale up or sustain operations at existing and planned manufacturing facilities, its customer relationships, business and results of operations may be adversely affected. 24. Bolt’s ﬁnancial results could vary materially from quarter to quarter and are difficult to predict. 25. Bolt utilizes subcontractor manufacturers to make its products. The failure of these manufactures to make products of sufficient quality on a timely basis or customers' refusal to purchase these products, could have a material adverse effect on Bolt's competitive advantage and ﬁnancial results. 26. Because Bolt manufactures components for consumer products that are applied to human skin, it is subject to, or affected by, certain product and manufacturing regulations, for which compliance can be costly and time consuming. In addition, it may be subject to personal injury or product liability claims as a result of human exposure from its customers’ products that may not be covered by insurance and could require it to pay substantial sums. 27. Bolt may not be able to protect adequately its patents and other intellectual property assets, which could adversely affect its competitive position and reduce the value of its products, and litigation to protect its patents and intellectual property assets may be costly. 28. Third parties may claim that Bolt infringes on their proprietary rights and may prevent Bolt from commercializing and selling its products. 29. Bolt relies in part on trade secrets to protect its technology, and its failure to obtain or maintain trade secret protection could limit its ability to compete.

RISK FACTORS Cont. Risk Factors — 60 30. Bolt depends on key personnel. 31. Bolt's management has limited experience in operating a public company 32. An increase in Bolt's shipping and freight costs could have a material adverse effect on Bolt’s ﬁnancial results because it may not be able to pass - through all of these increased costs to its customers. 33. If Bolt experiences a signiﬁcant disruption in its information technology systems, including security breaches, or if Bolt fails to implement new systems and software successfully, its business operations and ﬁnancial condition could be adversely affected. 34. Government regulation of Bolt’s business is extensive and the process for obtaining regulatory approvals is resource - intensive, with no assurances of obtaining approvals. 35. Changes in government regulation may require Bolt to modify its operations, including formulations that Bolt utilizes in its products. 36. Global economic and ﬁnancial market conditions, including severe market disruptions and the potential for a signiﬁcant and prolonged global economic downturn, could impact Bolt’s business operations in a number of ways, including, but not limited to, reduced demand in key customer end - markets, such as cosmetics and personal care products. Risks Related to the Proposed Business Combination 37. The ability of Golden Arrow stockholders to exercise redemption rights with respect to a large number of shares could deplete Golden Arrow’s trust account prior to the Business Combination and thereby diminish the amount of working capital of the ultimate holding company after the transaction (“Bolt Pubco”). 38. Directors and officers of Golden Arrow have potential conﬂicts of interest in recommending that stockholders vote in favor of approval of the Business Combination. 39. Golden Arrow stockholders will have a reduced ownership and voting interest after the Business Combination and will exercise less inﬂuence over management. 40. Golden Arrow Sponsor, LLC (the “Sponsor”) has agreed to indemnify Bolt Pubco for any excise tax to which it is subjected under the Inﬂation Reduction Act of 2022 as a result of stockholder redemptions made in 2023. The Sponsor will be permitted to sell shares of Bolt Pubco common stock after the close of the business combination to pay for the excise tax, which could negatively impact the stock price of Bolt Pubco’s shares. 41. Golden Arrow’s initial stockholders, directors, officers, advisors, and their affiliates may purchase shares or public warrants from public stockholders, which may reduce the public “ﬂoat” of Golden Arrow’s Class A common stock. 42. The Business Combination may not be completed by Golden Arrow’s business combination deadline in its organizational documents, as amended to date, and Golden Arrow may fail to obtain an extension of the business combination deadline. 43. There can be no assurance that the contemplated transaction will achieve the objectives of providing Bolt Pubco with sufficient capital, and if Bolt Pubco requires additional capital to fund its operations or expected growth, there can be no assurance that it will be able to obtain such funds on attractive terms or at all, and Bolt Pubco stockholders may experience dilution as a result. 44. Bolt and Golden Arrow have incurred and will incur substantial costs in connection with the Business Combination and related transactions, such as legal, accounting, consulting, and ﬁnancial advisory fees. 45. While Bolt and Golden Arrow work to complete the Business Combination, management’s focus and resources may be diverted from operational matters and other strategic opportunities. 46. Bolt’s operations may be restricted during the pendency of the Business Combination pursuant to terms of the Business Combination Agreement. 47. The announcement of the Business Combination could disrupt Bolt’s relationships with its customers, suppliers and others, as well as its operating results and business generally. 48. Uncertainty about the effect of the Business Combination may affect Bolt’s ability to retain key employees and integrate management structures and may negatively impact its management, strategy and results of operations. 49. The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisﬁed or waived, the Business Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be completed. 50. Bolt Pubco may incur successor liabilities due to conduct arising prior to the completion of the Business Combination. 51. Subsequent to the completion of the Business Combination, Bolt Pubco may be exposed to unknown or contingent liabilities and may be required to take write - downs or write - offs, restructuring and impairment or other charges that could have a signiﬁcant negative effect on its ﬁnancial condition, results of operations and the price of its securities, which could cause you to lose some or all of your investment. 52. The obligations associated with being a public company will involve signiﬁcant expenses and will require signiﬁcant resources and management attention, which may divert from Bolt’s business operations. 53. Bolt’s management and current resources may not successfully or effectively manage the transition to a public company. 54. Future sales of common stock after the consummation of the Business Combination may cause the market price of Bolt’s common stock to drop signiﬁcantly, even if Bolt’s business is doing well. 55. Following the Business Combination, outstanding warrants will become exercisable for Bolt Pubco’s common stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to Bolt Pubco’s stockholders. 56.
