So. Following ERs and pipelines updates. My main and quick uptakes. i cannot reconcile Pfizer 's guidance (11.5) with Biontech (4) ! I also find Moderna at 6 a bit surprisingly low. May be both cooking some Q4 ER. So total market size woud be less than 18 bil. I thought Moderna mishandles completly write offs vs Biontech and is spending too much compared to Biontech which managed to reduce its research spending substantially. Biontech is keeping its cash as it is! Moderna says it cannot really reduce its commitment before 26 when it will move "flex" ie depending on sales. In the meantime they will burn their cash as it is explained. Now Moderna is trying to be as transparent as possible notably on guidance 24 with a very low 1 bil for international markets which i believe is highly unprobable (or illogical?) versus the 2bil for the US. To conclude. Moderna is a great company but spending too much money vs its short term potential sales. Biontech surprised me by the quality of its management (write offs better handled, research spending cut meaningfully, keeping cash, even ER presentation a better product). Biontech will benefit fully from the narrative around cancer treatments. So stock might at the end perform better than Moderna that has not a lot in the short term. Moderna needs to find another gear in its playbook even if already impressive.
