I find the title of this whole thread to be extremely prejudicial. "Flatlining" implies that the sales are dying, like when a patient "flatlines" on the heart rate monitor. A more accurate statement would be that for Q1 2025 Tesla's sales were rather flat compared to Q4 2022. And that has to be put in perspective, since their Q4 2022 sales were impressive.
Well, titles have to succinctly communicate a idea. Let's explore, based on the evidence presented in this and other threads.
1. Q1 to Q1 has fallen drastically in 3 years, from 100% to 68% to now 35% (estimates, I cannot recall exactly). That is a radical downward trend that cannot be ignored.
2. Q4 to Q1 sales have been close to 0% for the most recent 3 years. That is a near flatline. One would expect to see significant improvements based on a myriad of economic moves that should stimulate sales. That has not transpired. (See Q1 to Q1 comparison).
3. Tesla recently (Q4 or Q1) cut prices. Yet we still see this decline. Tesla has announced yet more price cuts.
4. Tax breaks galore, should be stimulating demand. It's not.
5. Another thread, started today, shows Tesla is cutting back on performance breaks to presumably increase profits. Moving in the wrong direction, IMO.
6. The EV technology is not "unknowable" or magical. Tesla has the primary advantage of an early entry. It's a wildly overvalued company and as soon as the other majors have viable competing vehicles the big T's market share on their EVs will be slaughtered. As it stands now it only has a 5% share. That will probably be divided at least 3 or 4 ways in a few years.
This is not the sign of a confident healthy company from my business analyst perspective with open source information and a casual look at the facts surrounding the company.
Let's speculate for a moment on if the tax breaks and sales cuts go away. It's quite likely that Telsa sales would drastically have fallen more. They might have been unaffected, but that's unlikely. And there's no chance they'd have been better.
