**Adaptimmune Reports Q2 Financial Results and Provides Business Update**

*Q2 Tecelra sales of $11.1m with 16 patients invoiced represents >150% growth vs Q1 2025*

*Entered into a definitive agreement for the sale of TECELRA, lete-cel, afami-cel, and uza-cel cell therapies to US WorldMeds for $55 million upfront with up to $30 million in future milestone payments*

*Following the transaction, Adaptimmune has repaid its debt and is restructuring to maximize value from remaining assets, including PRAME and CD70 directed T-cell therapies*

Philadelphia, Pennsylvania and Oxford, United Kingdom--(Newsfile Corp. – August 13, 2025) - Adaptimmune Therapeutics plc (NASDAQ: ADAP) today reported financial results and provided a business update for the second quarter ended June 30, 2025.

**Adrian Rawcliffe, Adaptimmune's Chief Executive Officer:** "The launch of TECELRA continued to accelerate through Q2 with an increase of over 150% in patients invoiced and in revenue. The full network of ATCs is close to completion with 30 now accepting referrals. Our manufacturing organization continues to deliver with a 100% commercial manufacturing success rate through to the end of Q2. The transaction with US WorldMeds will ensure that patient access to TECLRA continues and also places lete-cel in capable hands leading up to its planned launch in 2026. As we noted when we announced the transaction on July 28, this deal follows an extensive review of strategic alternatives and represents the best path forward for Adaptimmune, our patients and stakeholders. Since closing the transaction on July 31, we have repaid our debt facility with Hercules Capital and are restructuring to support the assets transferred to US WorldMeds, and to maximize value from our remaining assets including programs targeting PRAME and CD70."

**Financial Results for the six months ended June 30, 2025**

● **Cash / liquidity position:** As of June 30, 2025, Adaptimmune had cash and cash equivalents of $26.1 million and Total Liquidity <sup>[1](#footnote-2)</sup> of $26.1 million, compared to $91.1 million and $151.6 million respectively, as of December 31, 2024.

● **Revenue**: Revenue for the three and six months ended June 30, 2025, was $13.7 million and $21.0 million respectively, compared to $128.2 million and$133.9 million for the same periods in 2024. Revenue from development activities decreased by 96% for the six months ended June 30, 2025, compared to the same period in 2024. This decline was primarily due to the termination of the Genentech collaboration in April 2024 which resulted in the recognition of a cumulative catch-up adjustment of $101.3 million for the six months ended June 30, 2024. The product revenue has increased due to product sales commencing following the FDA approval of TECELRA on August 1, 2024 .

● **Research and development (R&D) expenses:** R&D expenses for the three and six months ended June 30, 2025, were $23.0 million and $51.8 million respectively, compared to $40.4 million and $75.7 million for the same periods in 2024. R&D expenses decreased due to a decrease in the average number of employees engaged in R&D following the restructuring and reprioritization of activities that was announced in November 2024 and a decrease in subcontracted expenditure and manufacturing facilities expenses , offset by a decrease in offsetting reimbursements receivable for R&D tax and expenditure credits.

<sup>1</sup> Total liquidity is a non-GAAP financial measure, which is explained and reconciled to the most directly comparable financial measures prepared in accordance with GAAP below

------

● **Selling, general and administrative (SG&A) expenses:** SG&A expenses for the three months and six months ended June 30, 2025, were $18.5 million and $41.8 million respectively, compared to $19.1 million and $38.8 million for the equivalent periods in 2024. SG&A expenses increased due to restructuring charges for the restructuring program initiated in the fourth quarter of 2024 for which there was no equivalent in the same periods of 2024 which was partially offset by a decrease in share-based compensation expense due to forfeitures arising as a result of this restructuring program. Also, there was an increase in accounting, legal and professional fees due to fees relating to business development work.

● **Net loss:** Net loss attributable to holders of the Company's ordinary shareholders for the three months and six months ended June 30, 2025, were $30.3 million and $77.9 million respectively ($(0.02) and $(0.05) per ordinary share), compared to profits of $69.5 million and $21.0 million ($0.05 and $0.01 per ordinary share), for the equivalent periods in 2024.

As a result of the transaction with US WorldMeds and repayment of all sums under the loan agreement with Hercules Capital Inc, we consider that the cash and cash equivalents of the Company will be sufficient to meet our planned operating requirements through the 12 months following the filing of our Quarterly Report for the second quarter of 2025.
