Exhibit 99.1 FOR IMMEDIATE RELEASE AMYRIS, INC. REPORTS FOURTH QUARTER AND FULL YEAR 2022 FINANCIAL RESULTS • Fourth quarter Consumer revenue of $52.8 million increased 64% over the prior year and was another record quarter. Core revenue of $75.8 million grew 17% over the prior year • Full year Consumer revenue of $176.9 million increased 92% and outperformed prestige beauty industry growth of 15%. Core revenue of $269.8 million grew 44% over prior year • Use of cash for operating and investing activities sequentially improved each quarter; Q4 2022 down $102 million versus Q1 2022 • Actions taken to simplify portfolio, streamline management structure and deliver efficiencies Emeryville, CA – March 15, 2023 – Amyris, Inc. (Nasdaq: AMRS), a leading synthetic biotechnology company accelerating the world’s transition to sustainable consumption through its Lab-to-MarketTM technology platform and clean beauty consumer brands, today announced financial results for the fourth quarter and full year ended December 31, 2022. Q4 2022 Core revenue of $75.8 million grew 17% versus the prior year quarter driven by record Consumer revenue of $52.8 million, a 64% year-over-year increase for the quarter and 92% for the full year 2022. Amyris’ consumer brands continued their robust growth trajectory, outperforming prestige beauty industry growth of 15% according to NPD Group. Their year-end report confirms that every category in prestige beauty posted double- digit gains in 2022, with skin care, hair care, and color cosmetics growing 12%, 22%, and 18%, respectively. Amyris’ brands delivered 44%, 744%, and 145% growth, respectively, in these categories. “We have focused our brand leadership teams and are making differentiated portfolio choices placing our investment on attractive beauty categories such as skin care, hair care, color cosmetics, baby care and healthy aging with our flagship brands Biossance, JVN, Rose Inc., Pipette, Stripes and MenoLabs,” commented John Melo, President and Chief Executive Officer. “We have grouped our other, more nascent, brands under one leader to achieve economies of scale. We also expanded our Technology Access partnerships by signing an agreement with Givaudan for beauty and personal care, similar to existing partnerships with DSM in flavor and fragrance and Ingredion in food and beverage. We are actively working on a partnership for human health.” “We continued to have access to the necessary capital to fund our operations,” added Melo. “We secured $150 million in funding in the fourth quarter and communicated yesterday that we secured an additional $50 million to bridge us to the $200 million upfront cash payment from our strategic transaction, which is expected to close in the next 30-45 days following HSR review.” During 2022, Amyris reduced its use of cash for operating and investing activities sequentially each quarter from ($200) million in Q1 to ($189) million in Q2 to ($164) million in Q3 to ($97) million in Q4. The company also reduced its inventory holdings in Q4 and continues to build on these initial cost and cash improvements. Although management was not fully satisfied with the progress toward reducing operating expense, the company did substantially reduce the costs involved with inbound air shipping from Q3 to Q4 by $9.2 million or 72% and delayered its leadership structure effecting a $1.2 million initial restructuring charge. “We have much more to do on our Fit-to-Win agenda and are committed to delivering quarter-by-quarter improvements in profitability and cash generation from operations. We continue to be well-positioned to execute our Lab-to-Market strategy. We own the underlying science, we are the long-term producer at scale, we partner with leaders in their respective end-markets and bring some of the best performing clean beauty, health and

wellness products to consumers with our family of leading prestige brands. To fully leverage our assets and drive enterprise value, we are focused on efficiency, lowering our cost and significantly simplifying our portfolio. We expect these actions to meet our objective of ending 2023 as a self-sufficient enterprise,” concluded Melo. Revenue 1 Core revenue comprises Consumer and Technology Access revenue. Technology Access includes ingredient product revenue, R&D collaboration, and technology licenses. Core revenue excludes strategic transactions and other. Totals may not foot due to rounding. 2 Strategic Transactions & Other includes $143.6 million Flavors & Fragrances transaction (Q1 2021); $0.2 million discontinued ingredients value share (Q1 2021); and $10.0 million RebM transaction (Q2 2021) Q4 2022 Financial Highlights • Core revenue of $75.8 million increased 17% compared to Q4 2021 Core revenue of $64.8 million. Excluding $13.0 million of Q4 2021 technology license revenue attributable to joint ventures, Core revenue increased by 46%. Q4 2022 Core revenue included Consumer revenue of $52.8 million, an increase of $20.7 million or 64% compared to Q4 2021 and the seventh consecutive quarter of record growth. • Consumer revenue growth was primarily driven by the Biossance®, JVNTM and MenoLabs® brands. Overall performance within the Company’s clean beauty consumer portfolio outperformed the public peer group in year-over-year revenue growth. Direct-to-consumer sales grew 61% compared to Q4 2021, and retail sales through third party channels grew 66%. Biossance, Pipette®, JVN, and Rose Inc.® products were available in more than 14,000 physical locations compared to approximately 2,100 in 2021. • Technology Access revenue declined 30% compared to Q4 2021, primarily due to $13.0 million of Q4 2021 joint venture revenue. Ingredients product revenue decreased 12% to $14.3 million, reflecting temporary supply and working capital constraints, resulting in significant unfulfilled orders, as the business transitioned from higher cost toll manufacturing to lower cost internal sourcing from the new fermentation plant in Brazil. R&D collaboration revenue decreased 37% to $2.0 million. • Non-GAAP gross margin in Q4 2022 of $21.4 million (28% of revenue) decreased from $22.0 million (34% of revenue) in Q4 2021. Excluding the impact of technology license revenue in each period, non-GAAP gross margin increased from $9.0 million (17% of revenue) in Q4 2021 to $14.8 million (21% of revenue) in Q4 2022, reflecting Consumer revenue growth and margin expansion. • Non-GAAP cash operating expense of $148.3 million increased by $44.9 million compared to Q4 2021 due to increased headcount, consumer brand freight and fulfillment activities, and investments in consumer brands. • Adjusted EBITDA of ($156.8) million decreased $60.6 million, primarily due to higher operating expense. • Q4 2022 net loss was $149.8 million ($0.46 loss per diluted share) compared to net income of $37.8 million ($0.43 loss per diluted share) in Q4 2021. Non-cash mark-to-market adjustments related to changes in the fair value of debt and derivatives were $10.3 million favorable in Q4 2022 and $180.0 million favorable in Q4 2021. In addition, there was a favorable non-cash change in fair value of acquisition-related contingent consideration of $24.9 million in Q4 2022. • Total cash at the end of Q4 2022 was $70.6 million, compared to $24.6 million at the end of Q3 2022.

Excluding $153.8 million of 2021 strategic transactions, Adjusted EBITDA in 2022 decreased $260.1 million, primarily due to increased operating expense and higher ingredients cost of goods sold for contract manufactured intermediate and finished product. • Net loss was $528.5 million ($1.69 loss per diluted share), compared to a net loss of $270.5 million ($0.97 loss per diluted share) in 2021.

Q1 and 2023 Financial Outlook Total revenue (Core revenue plus strategic transaction) is expected to grow 95-100% for full year 2023 compared to 2022. The strategic transaction with Givaudan is expected to generate $200 million of license revenue in the second quarter. Core revenue (Consumer plus Technology Access revenue) is expected to follow approximate quarterly phasing of 15% of full year Core revenue expected in Q1, 25% expected in Q2, 27% expected in Q3, and 33% expected in Q4. Consumer brands are expected to continue to deliver industry leading growth in skin care, hair care, color cosmetics, baby care and healthy aging. We are prioritizing delivering on our cash use targets from sequential quarterly improvements in our cost base, both cost of goods sold and operating expense.

Capital expenditure is estimated at $55 million, 50% lower than 2022. No M&A activities are contemplated.
