Financial GuidanceBased on its current operating plan, Arvinas believes its cash, cash equivalents, and marketable securities as of December 31, 2024, is sufficient to fund planned operating expenses and capital expenditure requirements into 2027. Full Year and Fourth Quarter Financial Results Cash, Cash Equivalents, and Marketable Securities Position: As of December 31, 2024, cash, cash equivalents and marketable securities were $1,039.4 million as compared with cash, cash equivalents, restricted cash and marketable securities of $1,266.5 million as of December 31, 2023. The decrease in cash, cash equivalents and marketable securities of $227.1 million for the 12 months ended December 31, 2024 was primarily related to cash used in operations of $237.4 million (net of $150.0 million received from the Novartis agreements), inclusive of a one-time cash termination fee in the amount of $41.5 million related to the termination of our laboratory and office space lease with 101 College Street LLC in August 2024, the purchase of lab equipment and leasehold improvements of $1.8 million and $0.4 million of long term debt repayments, partially offset by proceeds from the exercise of stock options of $8.3 million, unrealized gains on marketable securities of $4.1 million and proceeds from disposal of equipment of $0.1 million. Research and Development Expenses: Research and development expenses were $348.2 million and $83.3 million for the year and quarter ended December 31, 2024, respectively, as compared with $379.7 million and $95.2 million for the year and quarter ended December 31, 2023, respectively. The decrease in research and development expenses of $31.5 million for the year was primarily due to a decrease in external expenses of $41.7 million, partially offset by an increase in compensation and related personnel expenses of $11.2 million, which are not allocated by program. External expenses include program-specific expenses, which decreased by $32.1 million, driven by decreases in our vepdegestrant and bavdegalutamide (ARV-110) programs of $27.9 million and $18.1 million, respectively, partially offset by increases in our ARV-102 and ARV-393 programs of $10.7 million and $5.4 million, respectively, and our non-program specific expenses, which decreased by $9.6 million. The decrease in research and development expenses of $11.9 million for the quarter was primarily due to a decrease in external expenses of $9.9 million, compensation and related personnel expenses of $0.5 million, which are not allocated by program, and other expenses of $1.5 million. External expenses include program-specific expenses, which decreased by $14.2 million, primarily driven by decreases in our vepdegestrant, luxdegalutamide (ARV-766) and bavdegalutamide (ARV-110) programs of $13.6 million, $6.0 million and $2.6 million, respectively, partially offset by increases in our ARV-102 and ARV-393 programs of $5.5 million and $1.3 million, respectively, and our non-program specific expenses of $4.3 million. General and Administrative Expenses: General and administrative expenses were $165.4 million and $34.1 million for the year and quarter ended of December 31, 2024, respectively, as compared with $100.3 million and $27.0 million for the year and quarter ended of December 31, 2023, respectively. The increase in general and administrative expenses of $65.1 million for the year was primarily due to a loss on the termination of our laboratory and office space lease with 101 College Street LLC in August 2024 of $43.4 million as well as increases in personnel and infrastructure related costs of $9.0 million, professional fees of $8.1 million and in developing our commercial operations of $4.2 million. The increase in general and administrative expenses of $7.1 million for the quarter was primarily due to increases in developing our commercial operations of $2.6 million, personnel and infrastructure related costs of $2.2 million and professional fees of $1.8 million. Revenue: Revenue was $263.4 million and $59.2 million for the year and quarter ended December 31, 2024, respectively, as compared with $78.5 million and $(43.1) million for the year and quarter ended December 31, 2023, respectively. The increase in revenue of $184.9 million for the year was primarily due to revenue from the Novartis agreements of $162.4 million, an increase in revenue from the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer of $21.7 million related in part to adjustments to revenue in 2023 from changes in contract estimates and year over year increases in revenue of $2.8 million and $2.2 million from the Bayer Collaboration Agreement and the Pfizer Research Collaboration Agreement, respectively, primarily due to changes in estimates in 2023 of the performance period duration under the agreements resulting from updated research timelines, offset by a decrease of $2.5 million of previously constrained deferred revenue related to our Oerth Bio joint venture, and a decrease of $1.8 million of revenue under the Restated Genentech Agreement as the performance period had concluded in 2023. The increase in revenue of $102.3 million for the quarter was primarily related to an increase in revenue from the Pfizer ARV-471 Collaboration Agreement totaling $63.8 million, primarily due to adjustments in 2023 to revenue from changes in contract estimates, as well as revenue from the Novartis agreements of $40.3 million, offset by a decrease in revenue from Bayer of $1.6 million related to the termination of the Bayer Collaboration Agreement in August 2024.

In recent years, among the new anesthetic sedation drugs launched on the market, Remazolam has undoubtedly aroused widespread concern in the industry. The drug was designed and synthesized by GlaxoSmithKline (GSK) in 1999, and after several corporate transfers, it was approved for market in China, the United States, Europe and other countries and regions around 2020. However, there are significant differences in the market performance of remazolam across countries. According to 2023 data, the drug's sales in China are about $40 million, while in the United States it is only $800,000, accounting for only 2% of the Chinese market. The reasons for this difference are worth exploring in depth. Remazolam is an ultra-short-acting GABAA receptor agonist whose design is inspired by midazolam and remifentanil, combining the properties of both. It is rapidly metabolized by carboxylesterases in the liver to produce inactive metabolites, resulting in rapid sedation resolution and short sedation recovery time. Remazolam's development history dates back to 1999, when GSK designed and synthesized the drug based on remifentanil's properties and filed a patent application. The patent was then transferred to TheraSci in the United Kingdom. Paion began developing the drug in 2008. Due to the instability of remazolam's free base, Paion developed remazolam benzenesulfonate, while Hengrui Pharmaceuticals adopted remazolam in the form of (toluene sulfonate) salt. At present, these two salt types of remazolam have been listed, of which Remazolam toluene sulfonate is only listed in China, while Remazolam benzenesulfonate is listed in China, Japan, the United States, Europe and other countries, but there are differences in indications. In the Chinese market, RenFCM obtained the Chinese market rights of Remazolam besylate in 2012, and was approved by the State Food and Drug Administration for sedation in colonoscopy in 2020, followed by the induction and maintenance of general anesthesia and the indication of bronchoscopic sedation. In the United States, Remazolam besylate was approved in July 2020 under the trade name Byfavo for a 30-minute sedation procedure marketed by Eagle. Remazolam besylate is approved for induction and maintenance of general anesthesia in Japan and South Korea. It is worth noting that in the first quarter of 2024, Paion was acquired by China's Renfu Pharmaceutical, which means that the global interests of Remazolam besylate have been vested in Renfu Pharmaceutical. Remazolam toluene sulfonate was first approved for sale in China in 2019 for indications including induction and maintenance of general anesthesia and sedation during colonoscopy. The difference in sales in the U.S. and China markets may be related to the different range of indications approved for remazolam in different countries. In the United States, Remazolam is only approved for procedural sedation, while in China, its approved indications include general anesthesia and sedation, and sales are significantly higher than in the United States. In addition, the difference in sales performance between China and the United States may also be related to concerns about remazolam metabolites. Remazolam is metabolized in the body to produce methanol, which may be further oxidized to formaldehyde and formic acid, and formaldehyde is potentially cytotoxic. As a result, the FDA requires remazolam to be administered only within 0.5 hours to avoid the buildup of methanol and its metabolites to dangerous levels. At present, other anesthetic sedatives commonly used in clinical practice, such as propofol, benzodiazepines (represented by midazolam), and α-receptor agonists (represented by dexmetropil), all have their own shortcomings. Although Remazolam still has room for improvement in some aspects, its unique advantages, such as rapid onset, rapid metabolism, rapid sedation recovery, etc., make it a potential application value in the field of anesthesia sedation. With the advancement of medical technology and the in-depth exploration of clinical applications, there may be an improved version of remazolam in the future, bringing new options to the field of anesthesia sedation.
