Ricardo Rodriguez
CFO & Treasurer at Aspen Aerogels
Our adjusted operating income of negative $2,900,000 was enabled by an adjusted OpEx run rate of 25,800,000 and our adjusted EBITDA was $4,900,000 in Q1. As a reminder, we define adjusted EBITDA as net income or loss before interest, taxes, depreciation, amortization, stock based compensation expenses and other items that we do not believe are indicative of our core operating performance. In Q4, these adjustments were meaningful and they included $286,600,000 in impairment of Plan two assets in Statesboro, Georgia, Dollars 9 Point 8 Million of restructuring and financing expenses linked to Plan two, dollars two point one million of stock based compensation, 5,800,000.0 of depreciation and amortization along with $1,900,000 of net interest expenses. Negative net income in Q1 of $301,200,000 or $3.67 per diluted share, assuming 82,200,000.0 shares would have been negative $4,800,000 or $06 per diluted share if we exclude the planned two asset impairment and restructuring costs of the quarter. Next, I'll turn to cash flow and our balance sheet.
