Exhibit 99.1

CONCORD, CA, May 2, 2024 - Cerus Corporation (Nasdaq: CERS) today announced financial results for the first quarter ended March 31, 2024.

•

First-quarter 2024 total revenue was comprised of (in thousands, except %):

•

U.S. ReCePI Phase 3 clinical trial successfully met primary endpoint for INTERCEPT Blood System for Red Blood Cells in cardiovascular surgery patients.

•

Received FDA approval of extended shelf life for INTERCEPT Platelet Processing Sets to 12 months, doubling the previous shelf life.

•

Advanced the LED illuminator program towards the Company’s target commercial launch in the EU in 2025.

•

Cash and cash equivalents and short-term investments were $72.2 million at March 31, 2024.

•

The Company is reiterating its full-year 2024 annual product revenue guidance range of $172 million to $175 million. Included in this range is full-year 2024 guidance for INTERCEPT Fibrinogen Complex, which is expected to be between $8 million to $10 million.

•

The Company expects to report GAAP net loss attributable to Cerus Corporation for the full-year 2024 while also remains committed to adjusted EBITDA breakeven for the full-year 2024.

“The Cerus team delivered against our plans for Q1, paving the way for the balance of 2024, with great progress on clinical milestones and a strong return to growth for our commercial business. The positive topline readout from ReCePI, the U.S. Phase 3 clinical trial for INTERCEPT Red Blood Cells, is a significant milestone for the program and for our efforts to potentially bring this product to the market globally,” stated William “Obi” Greenman, Cerus’ president and chief executive officer. “Red blood cells are the most commonly transfused blood components worldwide, and we are committed to providing the full INTERCEPT portfolio for all transfused blood components to our customers around the globe.”

“We are also on track for our expectations to post double-digit product revenue growth this year,” continued Greenman. “Strong sales of the INTERCEPT Blood System for Platelets in North America were the major contributor to the topline in the first quarter of 2024 compared to last year. As expected, we saw continued expansion in the U.S. alongside the near-complete adoption by Canadian Blood Services for three-quarters of that country’s blood supply. We also posted year-over-year growth in our U.S. INTERCEPT Fibrinogen Complex business, with large academic medical centers realizing the benefits of improved availability and reduced wastage. Now a third of the way through 2024, we are increasingly confident in our full-year product revenue growth trajectory.”

Product revenue during the first quarter of 2024 was $38.4 million, compared to $31.0 million during the prior year period. This strong year-over-year increase of 24% is further validation of the expected return to growth in our platelets and plasma business and increasing contribution from our INTERCEPT Fibrinogen Complex (IFC) business. The reported growth comes ahead of any potential positive impact from the recent FDA acceptance of platelet processing sets extended shelf life. First-quarter product revenue included sales of IFC, which were $1.9 million for the quarter, reflecting increased contribution from our recently-executed IFC sales agreements with large U.S. blood centers.

First-quarter 2024 government contract revenue was $5.0 million, compared to $7.5 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 Blood System for Red Blood Cells (RBCs) as well as efforts related to the development of next-generation pathogen reduction technology to treat whole blood and development of a lyophilized IFC. Reported government contract revenue during the first quarter of 2024 decreased versus the prior year period primarily due to completion of the U.S. Phase 3 ReCePI clinical trial for INTERCEPT RBCs.

Product gross profit for the first quarter of 2024 was $21.3 million, increasing by 23% over the prior year period. Product gross margin for the first quarter of 2024 was relatively stable year over year at 55.4% compared to 55.8% for the first quarter of 2023.

Total operating expenses for the first quarter of 2024 were $34.3 million, compared to $38.9 million for the same period of the prior year, reflecting a year-over-year decrease of 12%. Both R&D and selling, general, and administrative (SG&A) expenses saw meaningful decreases year over year, reflecting the efforts taken to optimize costs and drive to potential profitability.

R&D expenses for the first quarter of 2024 were $14.5 million, compared to $17.4 million for the first quarter of 2023. The primary driver for the decrease in R&D expenses was the restructuring implemented in the second quarter of last year and the completion of the Company’s ReCePI trial in the first quarter of 2024.

SG&A expenses narrowed for the first quarter of 2024 and totaled $19.8 million, compared to $21.6 million for the first quarter of 2023. The primary driver for the decrease in SG&A expenses was again the restructuring implemented in the second quarter of last year.

Net loss attributable to Cerus Corporation for the first quarter of 2024 was $9.7 million, or $0.05 per basic and diluted share, compared to a net loss attributable to Cerus Corporation of $15.6 million, or $0.09 per basic and diluted share, for the first quarter of 2023.

Non-GAAP adjusted EBITDA for the first quarter of 2024 was negative $2.7 million, compared to non-GAAP adjusted EBITDA of negative $9.8 million for the first quarter of 2023. As discussed during prior quarters, the Company expects full-year 2024 non-GAAP adjusted EBITDA breakeven, though over the near term, results may not be consistent quarter by quarter. For additional information, please see definitions and the reconciliation of this non-GAAP measure to net loss attributable to Cerus Corporation accompanying this release.

At March 31, 2024, the Company had cash and cash equivalents and short-term investments of $72.2 million, compared to $65.9 at December 31, 2023.

As of March 31, 2024, the Company had $65.0 million outstanding on its term loan and $20.0 million drawn on its revolving credit facility. The Company’s revolving line of credit allows for an additional $15 million.

For the first quarter of 2024, the Company generated positive operating cash flows of $2.0 million compared to cash used from operations of $8.5 million during the prior year period. These improvements were in-line with the Company’s expectations and will continue to be a focus area for the balance of 2024.

The Company continues to expect full-year 2024 product revenue will be in the range of $172 million to $175 million. Included in this range is full-year 2024 IFC revenue guidance between $8 million to $10 million.

The Company will host a conference call at 4:30 P.M. EDT this afternoon, during which management will discuss the Company’s financial results and provide a general business overview and outlook.

Cerus disclaims any obligation or undertaking to update or revise any forward-looking statements contained in this press release.

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, (x) revenue and direct costs associated with our government contracts and (xi)

restructuring charges. 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 non-GAAP adjusted EBITDA for the year ending December 31, 2024 to projected GAAP net loss attributable to Cerus Corporation for the year ending December 31, 2024 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.
