Unless my math is wrong, Lyft should be profitable in Q3

My math could be wrong. But here it goes.

It is based on page 8 of the earnings report https://s27.q4cdn.com/263799617/files/doc_financials/2023/q2/Lyft-Q2-2023-Earnings-Supplemental-Data.pdf

Lyft made 1020M in Q2 2023.
Lyft’s total costs were 1179M. The cost of revenue was 606M.
So opex cost was 1179M-606M = 573M.

Lyft reduced headcount by 26% in Q2 2023. So Q3 2023, opex should be around (1-.26)*573M = 424M.

Lyft guided to make 1113M with a 45% contribution margin. So lyft will make 500M in operating profit.

500M – 424M = 76M in net profit in Q3 2023.

If my math is correct, Lyft will join Uber in becoming profitable in Q3 2023.

75M per quarter is about 300M per year in net profit for Lyft in 2024.

Lyft has >1B in cash equivalents.

Lyft’s current market cap right now is 4B. The market is saying that the enterprise value is $2.2 billion.

Lyft has a network, brand and potential profit. But I still don’t know how to put a value on this stock. I don’t know how much their revenue can grow year over year.
Someone please check my math and call me out on my assumptions?
