Exhibit 99.1

Benson Hill Announces Second Quarter Financial Results

•Second quarter revenues of approximately $33.8 million, an increase compared to $23.5 millionin the same period of 2023, reflect the Company’s ongoing transition to an asset-light business model.

•Net loss from continuing operations, net of income taxes, was $18 million in the quarter, an improvement of $18.5 million in reported loss from the same period of the prior year. Adjusted EBITDA was a loss of $12.4 million, compared to a loss of $15.2 million in the same period of 2023, due primarily to expense reductions.

•Free cash flow loss in the first half of 2024 was $31.8 million, which was approximately 50 percent of the free cash flow loss in the first half of 2023.

•The Company ended the second quarter with $29.5 million of cash and marketable securities, expected to be sufficient to fund operations through the end of 2024.

•The Company provides updates on business milestones related to animal feeding trials, innovation pipeline advancements, and genetic market share in its Q2 Shareholder Letter.

ST. LOUIS, MO – August 8, 2024 - Benson Hill, Inc. (NYSE: BHIL, the “Company” or “Benson Hill”), a seed innovation company, today announced operating and financial results for the quarter ended June 30, 2024.

“The Benson Hill team showed focus and financial discipline and delivered significantly better operating results this quarter, while making strides in our transition to an asset-light licensing model. We also strengthened strategic partnerships that are crucial for our future growth,” said Deanie Elsner, Chief Executive Officer of Benson Hill. “Our highly advanced technology core has led to the development of what we believe to be the industry’s broadest and deepest R&D pipeline for soy quality traits. Our next priority is to implement several animal feeding trials with both commercial and academic partners, further validating the value our seed innovations deliver to end users.”

Progress Points

Progress across key initiatives in the second quarter included accelerations in the Company’s innovation pipeline, expanded feeding trials with the proprietary soybean portfolio, advancements with strategic partners, and exploration of new capital structures.

•The Company continued its rigorous focus on cash management, expecting to deliver cash runway through the end of 2024.

•Following a Q1 feeding trial, management reported that it will continue to validate the value of its seed innovations with end users. Nearly a dozen academic studies and commercial feeding trials are planned over the next 9 to 12 months in broiler chickens, turkey, swine, dairy, and salmon. These end-user market segments represent more than 80 percent of the 30 million U.S. soybean acres used in animal feed.1

•Management reiterated the competitive edge delivered by the innovation pipeline it announced last month. Seed advancements over the next decade are expected to feature herbicide-tolerant soybean varieties, varieties designed to meet end-user needs in animal feed, versions for soybean oil, and soybeans for future use in biofuel. The Company is on track to significantly expand its seed portfolio to

more than 35 varieties by 2025 and introduce herbicide-tolerant versions of its Ultra-High Protein, Low Oligosaccharide soybean in 2026, a year earlier than expected.

Second Quarter Results Compared to the Same Period of 2023

The following financial results exclude the former Fresh Segment and Seymour, Indiana, and Creston, Iowa, processing facilities reported in discontinued operations. The reconciliation of non-GAAP financial measures can be found in the accompanying financial tables. The combined results of the Company’s divested businesses have been reclassified and presented as discontinued operations, resulting in a significant reduction in reported revenues and related expenses.

•Reported revenues increased by $10.3 million in the second quarter of 2024, driven by higher grain sales of proprietary soybeans and higher revenue from partnerships and licensing agreements.

•R&D expenses were $7.5 million, a decrease of $2.9 million, or 27.7 percent. The decrease was driven by reduced personnel-related costs and other technology costs in connection with implementing the expanded Liquidity Improvement Plan. Benson Hill continues to invest in critical technology costs, facilities expenses (primarily related to the Crop Accelerator facility) and workforce-related expenses as it did in 2023, to drive innovation in feed, food, and fuel with its CropOS® technology platform.

•Selling, general, and administrative expenses were $10.2 million, an increase of $3.6 million, or 56 percent. The increase was due to a non-recurring $6.2 million reversal to stock-based compensation expense in 2023. Excluding this non-recurring expense decrease in 2023, there was a decrease of $2.6 million to other selling, general and administrative expenses driven by reduced personnel-related costs in connection with implementing the expanded Liquidity Improvement Plan.

•Net loss from continuing operations, net of income taxes, was $18 million, a decrease of $18.5 million in reported loss. Adjusted EBITDA was a loss of $12.4 million, compared to a loss of $15.2 million in the same period of the prior year, which represents a reduction in loss of $2.8 million.

•Cash and marketable securities of $29.5 million were on hand as of June 30, 2024.

First Six-Months Results Compared to the Same Period of 2023

The following financial results exclude the former Fresh Segment and Seymour, Indiana, and Creston, Iowa, processing facilities reported in discontinued operations. The reconciliation of non-GAAP financial measures can be found in the accompanying financial tables. The combined results of the Company’s divested businesses have been reclassified and presented as discontinued operations, resulting in a significant reduction in reported revenues and related expenses.

•Reported revenues in the first half of 2024 were $54.9 million, a decrease of $17.2 million, or 23.9 percent. The decrease was driven by recognition of revenue in 2023 from low margin trading volumes generated by business development efforts that did not repeat in 2024, partially offset by higher revenue from partnerships and licensing agreements during the six months ended June 30, 2024, compared to the same period in 2023. Revenue from domestic sales increased $5.8 million compared to the same period in 2023 due to higher grain sales of proprietary soybeans.

•R&D expenses were $14.4 million, a decrease of $8.6 million, or 37.3 percent. The decrease was driven by reduced personnel-related costs and other technology costs in connection with implementing the expanded Liquidity Improvement Plan.

2

•Selling, general, and administrative expenses were $25 million, an increase of $5.2 million, or 26.6 percent. Excluding a non-recurring $6.2 million reversal to stock-based compensation expense in 2023, these expenses decreased by $1 million, driven by reduced personnel-related costs in connection with implementing the Company’s expanded Liquidity Improvement Plan.

•Net loss from continuing operations, net of income taxes, was $44.3 million, an increase in reported loss of $1 million. Adjusted EBITDA was a loss of $19.5 million, compared to a loss of $29.7 million in the same period of the prior year which represents a reduction in loss of $10.2 million. Free cash flow loss in the first half of 2024 was $31.8 million, which was approximately 50 percent of the free cash flow loss in the first half of 2023.

Use of Non-GAAP Financial Measures

In this press release, the Company includes references to non-GAAP performance measures. The Company’s management uses these non-GAAP financial measures to facilitate financial and operational decision-making, including evaluation of the Company’s historical operating results. The Company’s management believes these non-GAAP measures are useful in evaluating the Company’s operating performance and are similar measures reported by publicly listed U.S. competitors, and regularly used by securities analysts, institutional investors, and other interested parties in analyzing operating performance and prospects. These non-GAAP financial measures reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the reconciliations to corresponding GAAP financial measures, may provide a more complete understanding of factors and trends affecting the Company’s business. By referencing these non-GAAP measures, the Company’s management intends to provide investors with a meaningful, consistent comparison of the Company’s performance for the periods presented. These non-GAAP financial measures should be considered supplemental to, and not a substitute for, financial information prepared in accordance with GAAP. The Company’s definition of these non-GAAP measures may differ from similarly titled measures of performance used by other companies in other industries or within the same industry. In addition, the Company has and may in the future modify how it calculates non-GAAP performance measures. Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the Company’s condensed consolidated financial statements and publicly filed reports in their entirety. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the tables accompanying this press release.
