USA [Financial statement/PP&E depreciation] Question about a specific public company's PP&E depreciation

[AndrewMew]

Hello! I am reading the financial statement of a public company named OUSTER. Based on the 2022 Q1 report, the accumulated depreciation in Property and Equipment, net (PP&E) is 12,289 while this item in the 2021 Annual report is 10,740. Therefore, I believe the increase in PP&E depreciation during 2022 Q1 is (12,289-10,740) which is 1549.

Now I would like to cross-validate this number using the balance sheet and the cash flow sheet. From the balance sheet of the 2022 Q1 report, the PP&E net value is 8,968 while this item in the 2021 annual report is 10,054. The following equation should be held:

{2021_annual_PP&E} - {PP&E depreciation in 2022 Q1} + {PP&E investment in 2022 Q1} - {Sale of PP&E in 2022 Q1} = {2022_Q1_PP&E}

Here:

1. {2021_annual_PP&E} = 10,054
2. {PP&E depreciation in 2022 Q1} is the value that I would like to cross-validate. Based on the financial statements, this value should be 1549
3. {PP&E investment in 2022 Q1} = 416. I found this number from the CFI in the cash flow sheet from 2022 Q1 report
4. {Sale of PP&E in 2022 Q1} = 275. I found this number from the CFI in the cash flow sheet from 2022 Q1 report
5. {2022_Q1_PP&E} = 8,968

However, the calculation result is not 1549. I believe there must be some errors in my calculation procedure. Can anyone help me figure out the mistake I made?

Totally beginner in financial analysis. Thank you in advance!

"Therefore, I believe the increase in PP&E depreciation during 2022 Q1 is (12,289-10,740) which is 1549."

Read near top of Page 15 of the Q1 Report.
Tells you that depreciation expense for the quarter was $1.3 million.

The sold PP&E is excluded from the PP&E depreciation.
