Thanks, Mike. Good morning, and thank you for joining the call. I would also like to welcome the new listeners on today's call. We believe Algoma's results underscore a compelling investment opportunity, and we look forward to sharing more details. We are certainly excited as we move closer to an Algoma public listing later this year. Before we get into those details, I'm happy to report that we had a very successful June quarter, the first quarter of our fiscal year ending 31st March 2022.
On our last quarterly call, we presented guidance for the first quarter, and I'm happy to say that we met and exceeded these targets. We shipped 610,000 net tons in the quarter. Shipments were similar to prior quarter and up 47% from 416,000 net tons in the same quarter of last year, primarily as a result of a return to run rate utilization levels compared to the pandemic lows experienced last year.
Our steel revenue was $765 million in Q1, up 21% from $633 million in the prior quarter, driven by higher net sales realization due to unprecedented demand. In comparison to the same quarter of the prior fiscal year, revenues increased by $423 million as net sales realization were higher by $439 per net ton, resulting in a 124% increase in steel revenue.
As a reminder, both our contract and spot orders are subject to a pricing lag due to price mechanics and mill lead times. We have started to see these positive results flow through our earnings. And what is even more positive is that prices have continued to rise now for 53 consecutive weeks.
On the cost side, Algoma's cost of goods sold per ton increased slightly quarter-over-quarter as some commodity price increases have an effect on selected raw material inputs. Offsetting these increases, Algoma remains focused on our cost saving initiatives, and to date, we have captured run rate savings of approximately $42 million on an annualized basis, and we remain on track to reach our $50 million target. Further to that, based on our employees' contributions and our enhanced earnings performance, Algoma is accruing for increased profit sharing.
When compared to the same quarter of last year, cost of steel products sold per ton is approximately 3% higher. Please keep in mind that Algoma was eligible and we did receive benefits under the Canadian Emergency Wage Subsidy program last year as the pandemic impacted our business substantially, which allowed us to keep our employees working during this period of low production volume and mitigated high fixed cost on a per ton basis.
We generated $281 million of adjusted EBITDA during the quarter, which beats our guidance of $250 million compared to $167 million of adjusted EBITDA in the prior quarter. We are continuing to reap the rewards of even higher pricing moving through our results. However, due to the lagging nature of our order book, we expect to realize today's higher prices in the subsequent months and fiscal quarters.
With the earnings performance, we generated $275 million of cash from operations prior to changes in working capital. We fully repaid our ABL during the quarter. And after considering CapEx, cash interest expense and changes in working capital, we ended with $21 million of cash on the balance sheet, which gives us liquidity of approximately $304 million, in line with our guidance. With the impact of higher selling prices on our accounts receivable and the traditional restocking of inventories after the winter period, there was a usage of working capital during the quarter. I will get into these changes in more details on Slide 7.
Please note that the chart shown on Slide 7 only includes inventory, trade receivables and payables net of prepaids, which are the main drivers of working capital movement. Before we get into the details, I want to reiterate that our financial statements are prepared using the U.S. dollar as our functional currency and Canadian dollar as our presentation currency. As a result, there was an impact of exchange variation on the reported financial results.
While there was not a significant change in rate quarter-over-quarter, there was a large impact when comparing year-over-year results as the exchange rates at June 30, 2020, was $1.3576 compared to June 30, 2021's closing rate of $1.2394. The significant appreciation of the Canadian dollar versus its U.S. counterpart has an impact on balance sheet items as they are converted at the end of period rate.
When compared against the prior quarter, inventories increased by $55 million over the quarter from $415 million to $470 million. Raw material inventory increased by $18 million as we restocked inventories from the lows at the end of the March quarter. In addition, there was an increase in the value of work in progress and finished goods inventory totaling approximately $37 million. This is attributable to higher carrying cost of inventory as cost of certain raw material increased and higher volume of work-in-progress inventory, which was produced to accommodate the planned maintenance to one of our steelmaking vessels in the next quarter, mitigating impacts to shipments.
Accounts receivable increased by $54 million from the prior quarter. This increase is attributable to the significant increase in sales realization in this rising price environment. Accounts payable balances increased by $23 million, having a favorable impact on working capital. This is attributable to the resumption of normal raw material shipment over the quarter coming off of the winter slowdown where the Great Lakes are not navigable for vessel traffic. With these solid results behind us, the logical question that arise is how we expect our performance to be over the next quarter.
As you can see on Slide 8, there has been a significant increase in the index price of steel from August of last year till now. Strong demand, coupled with extremely low customer inventory levels across the supply chain continue to support full flat-rolled steel price above historical peaks. Demand from key end markets include automotive remains strong, and we expect this to continue into next year. We feel that the investments we are making in our plate mill will serve as well as traditionally as rolled plate is priced higher than hot-rolled coil. Today, this relationship has inverted. However, with infrastructure spending, we feel the traditional relationship will return and Algoma will reap benefit at that point with higher production capacity and broader market reach for our products.
With the macroeconomic drivers in North America market, we believe that price will remain elevated for the foreseeable future with the new paradigm for steel selling prices. All of these factors provide for very positive forward-looking guidance. Shipments in the second quarter of 2022 ended September are expected to be in line with the current quarter. We expect shipment volume of over 600,000 net tons.
As mentioned earlier, we do expect to take a 2-week maintenance outage for the annual reline of one of our steelmaking vessels. Net sale realizations are again expected to be directionally higher as we expect to see price climb month-by-month in parallel with the significant index price increase we have experienced with further upside in October to December quarter. We can expect adjusted EBITDA performance of approximately $400 million plus/minus.
With the strong earning of performance, we are positioned to generate significant free cash flow. By the end of September, we anticipate we may have over $300 million of result in cash and full access to our undrawn revolving credit facility. Also reflected in this guidance is the reduction of special contribution to our defined benefit pension plan in response to us having reached 85% funding on a solvency basis. This significant liquidity is expected to provide us the opportunity to improve our capital structure and pursue other strategic initiatives.
To take us further through our strategic activities, I will now turn over the call to Mike.
