AMG had a net debt position of $265.3 million as of September 30, 2021. This decrease was mainly due to the issuance of 3.1 million shares for net proceeds of $119 million in April 2021, offset by the significant investment in growth initiatives during the quarter, especially in our vanadium expansion in Ohio, which reduced AMG’s restricted cash balance.
AMG continued to maintain a strong balance sheet and adequate sources of liquidity during the third quarter. As of September 30, 2021, the Company had $319 million in unrestricted cash and cash equivalents and $170 million available on its revolving credit facility. As such, AMG had $489 million of total liquidity as of September 30, 2021.
Net Finance Costs
AMG’s third quarter 2021 net finance costs were $7.5 million compared to $4.5 million in the third quarter of 2020. This increase was mainly driven by higher foreign exchange losses during the quarter.
AMG capitalized $3.8 million of interest costs in the third quarter of 2021, in line with prior year, driven by interest associated with the Company’s tax-exempt municipal bond supporting the vanadium expansion in Ohio.
AMG’s third quarter 2021 SG&A expenses were $33.8 million compared to $29.6 million in the third quarter of 2020, with the variance driven largely by increased strategic project and personnel costs. The prior period personnel cost had been reduced by cost reduction efforts in response to the onset of the pandemic.
For 2021, we reiterate our expectation to sequentially improve our EBITDA quarter-over-quarter for the year.
Given the current market conditions, we expect EBITDA to exceed $150 million for full year 2022, and we expect to reach $50 million of quarterly run-rate EBITDA by the end of 2022, as our vanadium expansion project concludes ramp-up.
