Conference Call Today at 4:30 pm ET

CONCORD, CA, August 5, 2025- Cerus Corporation (Nasdaq:CERS) announced financial results for the second quarter ended June 30, 2025, and provided a business update.

“With our singular focus to advance blood safety and availability around the globe by establishing INTERCEPT as the standard of care, this quarter’s commercial results are evidence of the progress we are making in multiple geographies and across our INTERCEPT product portfolio. The early launch and adoption of our next generation, LED-based INT200 illumination device continues to surpass our expectations around performance and customer experience, and advancements in our product development pipeline are encouraging, including the early resubmission for RBC CE Mark and the recent DoD award for the CRYO-First study,” said William “Obi” Greenman, Cerus’ president and chief executive officer.

“In addition, the continued strong commercial and financial execution in Q2 resulted in record product sales, a year-over-year narrowing of net loss attributable to Cerus, and another quarter of positive non-GAAP adjusted EBITDA,” continued Greenman. “Given the anticipated sales trajectory, we are raising our full-year 2025 product revenue guidance today.”

Revenue

Product revenue during the second quarter of 2025 was $52.4 million, compared to $45.1 million during the prior year period. This year-over-year increase of 16% was led by growth in IFC and global platelet sales. Second-quarter product revenue included U.S. sales of IFC, which were $5.6 million, up from $2.0 million during the prior year period.

Second-quarter 2025 government contract revenue was $7.7 million, compared to $5.4 million during the prior year period. Our government contract revenue was comprised of funding associated with research and development (R&D) activities related to the INTERCEPT RBC program as well as efforts related to the development of next-generation pathogen reduction technology to treat whole-blood and development of lyophilized IFC. The year-over-year increase was primarily driven by increasing enrollment in the Phase 3 RedeS trial for the INTERCEPT RBC system covered under the Company’s 2016 agreement with BARDA and the activities for the advancement of the INTERCEPT RBC system covered under the Company’s 2024 BARDA contract.

Product Gross Profit and Margin

Product gross profit for the second quarter of 2025 was $29.0 million, increasing by 17% over the prior year period. Product gross margin for the second quarter of 2025 was 55.2% compared to 54.7% for the second quarter of 2024. A number of offsetting factors resulted in relatively stable product gross margin in the second quarter of 2025.

Operating Expenses

Total operating expenses for the second quarter of 2025 were $40.1 million, compared to $33.9 million for the same period of the prior year, reflecting a year-over-year increase of 18%. Both R&D and selling, general, and administrative (SG&A) expenses increased year-over-year, reflecting investments in our business to drive future revenue growth.

R&D expenses for the second quarter of 2025 were $18.9 million, compared to $15.0 million for the second quarter of 2024. The primary drivers for the increase in R&D

expenses were related to development costs on INT200, the new LED-based illumination device, higher government contract costs incurred to support the higher government contract revenue and higher employee compensation expenses tied to cost-of-living adjustments which became effective earlier in the year.

SG&A expenses totaled $21.2 million for the second quarter of 2025, compared to $19.0 million for the second quarter of 2024. The primary driver for the increase in SG&A expenses was higher employee compensation expenses tied to cost-of-living adjustments which became effective earlier in the year.

Net Loss Attributable to Cerus Corporation

Net loss attributable to Cerus Corporation for the second quarter of 2025 was $5.7 million, or $0.03 per basic and diluted share, compared to a net loss attributable to Cerus Corporation of $5.8 million, or $0.03 per basic and diluted share, for the same period of the prior year. Net loss attributable to Cerus Corporation for the first half of 2025 was $13.4 million compared to net loss attributable to Cerus Corporation of $15.5 million for the first half of 2024.

Non-GAAP Adjusted EBITDA

Non-GAAP adjusted EBITDA for the second quarter of 2025 was positive $0.9 million, compared to non-GAAP adjusted EBITDA of positive $0.8 million for the same period of the prior year. Non-GAAP adjusted EBITDA for the first half of 2025 was a positive $1.1 million compared to non-GAAP adjusted EBITDA of negative $1.9 million for the first half of 2024.

The Company remains committed to its goal of achieving positive, full-year 2025 non-GAAP adjusted EBITDA. For additional information, please see definitions and the reconciliation of this non-GAAP measure to net loss attributable to Cerus Corporation accompanying this release.

Balance Sheet and Cash Flows

At June 30, 2025, the Company had cash, cash equivalents, and short-term investments of $78.0 million, compared to $80.5 million at December 31, 2024. The Company’s revolving line of credit allows for an additional $15.0 million as of June 30, 2025, which is dependent on eligible assets supporting the borrowing base.

For the second quarter of 2025, cash used from operations totaled $2.4 million compared to $0.4 million generated during the same period of the prior year. Cash use from operations in the second quarter of 2025 was tied to an increase in working capital, namely inventory in support of the expected growth.

Increasing Full-Year 2025 Product Revenue Guidance

Given the strong performance during the first half of 2025, coupled with increasing conviction about expected second half growth, the Company now expects full-year 2025 product revenue will be in the range of $200 million to $203 million. These revisions include increased IFC guidance, which the Company now expects to be between $16 million to $18 million for 2025. Previously, the Company’s 2025 product revenue guidance

range was $194 million to $200 million, including 2025 IFC revenue guidance between $12 million and $15 million.

Use of Non-GAAP Financial Measures

We define adjusted EBITDA as net loss attributable to Cerus Corporation as reported on the consolidated statement of operations, as adjusted to exclude, as applicable for the

reporting period(s) presented, (i) net loss attributable to noncontrolling interest, (ii) provision for income taxes, (iii) foreign exchange (loss)/gain, (iv) interest income (expense), (v) other income (expense), net, (vi) depreciation and amortization, (vii) share-based compensation, (viii) goodwill and asset impairments, (ix) costs associated with our noncontrolling interest in our joint venture in China and, (x) revenue and direct costs associated with our government contracts. We are presenting this non-GAAP financial measure to assist investors in assessing our operating results. Management believes this non-GAAP information is useful for investors, when considered in conjunction with Cerus’ GAAP financial statements, because management uses such information internally for its operating, budgeting and financial planning purposes. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of Cerus’ operating results as reported under GAAP. This non-GAAP financial measure should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. This non-GAAP financial measure is not necessarily comparable to similarly-titled measures presented by other companies.

Investors should note that Cerus has not provided a reconciliation of anticipated positive non-GAAP adjusted EBITDA for the year ending December 31, 2025 to projected GAAP net loss attributable to Cerus Corporation for the year ending December 31, 2025 because certain items such as share-based compensation that are components of GAAP net loss attributable to Cerus Corporation cannot be reasonably projected due to the significant impact of changes in Cerus’ stock price and other factors. These components of GAAP net loss attributable to Cerus Corporation could significantly impact the reported GAAP net loss attributable to Cerus Corporation.
