Strata Acquires Keystone Perfusion, Creating Integrated Organ Recovery Platform, Diversifying into Other Medical Services

•Keystone is expected to generate approximately $65 million of revenue and approximately $13 million of Adjusted EBITDA(1) in the full-year 2025, with revenue expected to grow more than 50% in 2025 versus 2024

•Acquisition follows multi-year partnership between Strata and Keystone whereby Keystone has successfully recovered hundreds of organs on behalf of Strata customers

•$124 million acquisition represents an approximate 9x multiple of 2025 estimated Adjusted EBITDA(1); Keystone's go forward Free Cash Flow(1) conversion is expected to be approximately 80%

NEW YORK — (September 16, 2025) — Strata Critical Medical, Inc. (Nasdaq: SRTA, "Strata" or the "Company"), formerly known as Blade Air Mobility, Inc. (Nasdaq: BLDE), today announced that it has completed the acquisition of Keystone Perfusion Services LLC ("Keystone"), one of the largest organ recovery and normothermic regional perfusion ("NRP") service providers to the transplant industry and an industry leader in perfusion and other critical medical solutions for hospitals in non-transplant surgeries nationwide.

This transformative acquisition, combined with Strata's existing capabilities and its Trinity Medical Solutions subsidiary, creates the only full-service organ transplant service provider offering surgical recovery, NRP services, air and ground logistics and organ placement services while supporting any preservation or machine perfusion provider a customer may choose.

"Having partnered with Lou, Mike, Christie and the entire Keystone team for hundreds of successful organ recoveries using NRP, we've had a front-row seat to their unmatched skill coupled with leading tech-enabled communication and quality control," said Strata Co-CEO Will Heyburn. "Like our acquisition of Trinity, this opportunity was born out of the mutual respect and trust we built through a successful commercial relationship, giving us the first-hand experience we need to offer Keystone's services to our nationwide customer base with absolute confidence."

"Keystone’s NRP and recovery services enable us to say ‘yes’ to our transplant customers' requests to provide these additional critical services directly, which we have historically arranged for them through third-parties,” said Melissa Tomkiel, Co-CEO of Strata. “At the same time, we're establishing a platform to provide non-transplant-related solutions to new healthcare customers, a core tenet of our growth strategy following the divestiture of our passenger business, with such services representing more than half of Keystone's revenue."

(1) We have not reconciled the forward-looking Adjusted EBITDA and Free Cash Flow guidance included above to the most directly comparable GAAP measure because this cannot be done without unreasonable effort due to the variability and low visibility with respect to certain costs, the most significant of which are incentive compensation (including stock-based compensation), transaction-related expenses, and certain fair value measurements, which are potential adjustments to future earnings. We expect the variability of these items to have a potentially unpredictable, and a potentially significant, impact on our future GAAP financial results.

Exhibit 99.1

Tomkiel added, "The non-transplant services provided by Keystone represent a new addressable market opportunity for Strata in fragmented medical sectors with significant organic and inorganic growth opportunities.”

“Clients are seeking a trusted partner that not only delivers clinical expertise and exceptional service but a comprehensive solution encompassing rapidly deployable surgical and perfusion teams, equipment, logistics support, disposables, and critical transportation," said Louis Verdetto, CEO of Keystone Perfusion. "By joining Strata, Keystone becomes part of a platform built to do exactly that—across transplant services, perfusionist staffing for cardiac surgery, and the broader hospital sector.”

Verdetto added, “Our customers will see continuity in the people and services they already rely on, with the added benefit of broader infrastructure, advanced logistics, and integrated transportation capabilities that not only ensure every case runs seamlessly from recovery to delivery, but also create meaningful efficiencies and growth opportunities as we scale nationally.”

Transaction Details

•$124 million in upfront consideration consists of approximately 88% cash and 12% stock

•Stock consideration is subject to a minimum four-year lock-up, extended to seven years if Keystone management does not remain employed by Strata for a minimum of three years post-close

•Upfront consideration represents an approximate 9x multiple of 2025 estimated Adjusted EBITDA(1) of approximately $13 million; Keystone's go forward Free Cash Flow(1) conversion is expected to be approximately 80%

•By achieving gross profit growth of approximately 25% in each of 2026, 2027, and 2028, Keystone management may receive up to $23 million in earn-outs, paid in cash or up to 50% stock at Strata's option

•Founder and CEO Louis Verdetto, Michael Hancock and Christie Campbell all will remain in their current roles at Keystone post-closing and are eligible to participate in earn-out payments through 2028

•Additional information can be found in our acquisition presentation and our 8-K, both available at ir.srta.com

Financial Outlook

We are updating our 2025 financial guidance to reflect the Keystone acquisition. The financial outlook below reflects the passenger business classified as discontinued operations for all periods in 2025.

For the full year 2025:

•Revenue: $180 to $190 million

•Adjusted EBITDA(1): $13 to $14 million

Full year 2025 guidance reflects the impact of the Keystone acquisition only from the closing date onward, consistent with the Company’s methodology for future reporting. Assuming the Keystone acquisition closed on January 1, 2025, the company would expect to generate:

•Revenue: $225 to $235 million

•Adjusted EBITDA(1): $22 to $24 million

We expect to provide 2026 guidance, inclusive of the impact of the Keystone acquisition, at our investor day, scheduled for the afternoon of Monday November 17, 2025 in New York City. We will provide more details regarding the investor day in the coming weeks.
