Thanks, Jim. Turning to Slide 6. I will walk through our operating metrics for Stage I on the left-hand side of the page and our Stage II metrics on the right.
In the Upstream business, we produced 11,151 metric tons of REO in concentrate in the quarter, a 4.5% increase over the last year and over 20% more than Q4 mainly due to near record uptimes and higher feed rates. This higher production, combined with our focus on efficiently increasing NdPr production, we discussed in detail last quarter, resulted in strong sales of REO and concentrate of 9,332 metric tons. This is down year-over-year as we consumed nearly 1/4 of our concentrate production for downstream operations versus last year when we had all of our concentrate production available for sale.
Our realized price of REO in concentrate declined to $4,294 per metric ton due to the overall weak market pricing in rare earth materials. As we look at Q2, should prices hold in the mid-$50 per kilogram range for NdPr, we would expect pricing to be down mid-single-digit percentages sequentially as we deal with the slight lag in price realizations.
Moving to the right side of the slide. As Michael mentioned in February, NdPr production volumes were roughly in line with our Q4 output at 131 metric tons. As we look at Q2, given some of the continued optimization steps we are taking here in April and May, even with our 1-week plant shutdown, which was just completed, we would expect NdPr production to roughly double in Q2. And as Jim stated, we would expect much more meaningful step-ups in production in the back half of the year, which Michael will discuss shortly.
Looking at NdPr sales volumes. We sold 134 metric tons of NdPr on an oxide equivalent basis, mainly to customers in Japan. I would note that NdPr sales volumes will naturally lag production volumes as significant portions of our production are being toll processed into metal in Vietnam, as we've discussed in prior quarters. This is part of the working capital investment you see on our balance sheet as we scale this midstream business. The lag on any given unit of production, of course, depends on a variety of factors, but we generally are seeing at least 2 to 4 months as we continue to fill the tolling channel and convert production into sales.
Lastly, on the far right, you'll see our realized price per kilogram of NdPr was $62, which, as we mentioned in February, exhibits a more notable lag to market prices than that of concentrate. With Q1 sales prices, primarily based off fourth quarter market indices. As such, we expect Q2's realized prices to decline approximately 20% of following the trend we saw in market prices for Q1 over Q4.
Turning to Slide 7. Revenues declined from last year to $48.7 million driven by the lower concentrate realized pricing and sales, partially offset by beginning of sales of NdPr oxide in metal. Sequentially, sales improved 18% due to the increase in sales of NdPr oxide and metal. Adjusted EBITDA and related margins declined year-over-year to negative $1.2 million and negative 3%, respectively, in the quarter. Primarily due to lower realized pricing for concentrate just discussed, which impacts EBITDA on a dollar-for-dollar basis as well as the current subscale production of separated products.
Adjusted EBITDA was impacted by a $6 million inventory reserve taken in Q1, which was included in cost of sales on the P&L. So before this reserve and the cost for magnetics embedded in our operations, our concentrate business remains nicely profitable, even at multiyear lows in commodity prices.
As we discussed last quarter, our early cost of production of separated products is higher than our expected costs once we reach more normalized production levels, given we are staffed for higher production rates and early production often requires additional processing, labor and certain rework that should not recur once operations normalize.
With these impacts and the rapid deterioration in market prices, we reserved for certain inventory where costs are currently estimated to exceed net realizable value. This is not unexpected as we ramp up the plant and may continue for a short period as we finish our initial optimization. That said, we remain steadfastly confident in ultimately achieving a best-in-class per unit cost profile. And we should see improvements later this year as our production ramps towards run rate levels.
On the far right, you will see adjusted diluted EPS was a $0.04 loss driven by the lower adjusted EBITDA and higher depreciation from the significant amount of assets placed in service over the last year. This was partially offset by lower tax expense in the quarter due to lower pretax income.
GAAP EPS was also impacted by a $46.3 million gain associated with the early extinguishment of the majority of our 2026 convertible notes, which leads me to Slide 8.
We haven't shown a slide like this in some time, but given the significant transactions that took place in the quarter, we thought we would give an updated rundown of the changes. So running through the transactions.
First, in early March, we issued $747.5 million of new 3% convertible notes due in 2030, strengthening an already solid balance sheet by materially extending the maturities on our debt with the primary use of proceeds being to buy back a large portion of our existing 2026 notes. The new notes convert at a 40% premium to the share price on the date of the transaction or $21.74 per share on a stand-alone basis. But in connection with this offering, we entered into cap call transactions to effectively increase the premium of the 2030 notes to 100% or $31.06 per share.
The 3% coupon on the notes while higher than our near-dated debt reflecting the current interest rate environment remains below the current market rate we received on our cash investments, continuing to provide positive carry. And when including the cost of the capped calls, the all-in cost of the new notes is approximately 4.7% until conversion, a very positive outcome for the company.
As mentioned, the primary use of proceeds from the offering was to repurchase $480 million of our existing 2026 convertible notes which we did for $428.6 million or $0.89 of par value, which drove the $46.3 million gain in the quarter.
I would also note that we made the election to pay any principal remaining on the 2026 notes in cash at maturity. So the shares underlying the remaining principle will fall out of our diluted share count calculations in future periods. Importantly, we also used $200.8 million to buy back 13 million shares, a fairly substantial retirement of 7.3% of the company's outstanding shares.
We have always said that we would be opportunistic on capital return, given how we have positioned our balance sheet and given the confidence we have in our go-forward plan as well as the substantial drawdown in our market value, in line with the current down cycle in NdPr prices, we saw a significant opportunity to create value for shareholders while maintaining a prudent balance sheet.
As of March 31, we are roughly net debt neutral after undertaking all of these transactions and continuing to invest in the required working capital to grow our midstream business. And despite weak commodity prices, we continue to expect our balance sheet to remain robust with several cash contributors in the short and medium term beyond our base business, including significant product prepayments in our magnetics business as well as the substantial cash impacts of both our 45X and 48C tax credits, which I will discuss in more detail in a moment.
To term out the vast majority of our debt maturities while capturing the value of both our depressed share price and the below par price of our existing notes, we expect will prove pression as we look to a stabilization and recovery in our commodity prices as well as continued execution on our business plan.
To put all of these transactions into a simpler form, particularly as it relates to the impacts on our share count, we have laid out the changes on the left-hand side of the slide. Please note that our GAAP diluted share count does not incorporate the anti-dilutive impact of the capped call transactions, which you can see incorporated in our adjusted figure on the bottom.
And the table on the right side of the page walks you through the bridge from the left-hand side to a calculation of market cap and enterprise value, which would capture the principal of the convertible notes in the debt calculation and not in shares or market cap.
Regarding our cash balance. I'd note that subsequent to quarter end and so not reflected on our Q1 balance sheet, we received an initial prepayment of $50 million for magnetic precursor products in Stage III and we expect a further $100 million of payments, assuming we hit our operational hurdles over the next 12 months. In addition, we expect approximately $20 million in cash from the IRS when we file our tax return here soon for 2023.
And lastly, while timing and monetization options are still not finalized, we expect to realize $58.5 million from our 48C tax credits that we've discussed in the not-too-distant future. All told, that is over $220 million in sources of cash that we can expect beyond our base business operations.
As it relates to cash flow in this first quarter, our cash from operations, in particular, our working capital was impacted by several discrete items, which is bridged in a slide in the appendix. I would flag that our major NdPr metal deliveries were booked very late in the quarter, so cash was received in April. Further, we continue to build work in process inventory and finished goods inventory as we begin to further scale downstream production here in the next several months. And importantly, as we continue to feed the toll metal sales channel.
Lastly, we had a significant onetime cash spend on transaction costs in the quarter from costs recorded in both the Q4 and Q1 P&L and made our typical Q1 annual bonus payouts to employees. Regarding gross CapEx, we spent approximately $51.8 million in the quarter, in line with our full year outlook of $200 million to $250 million, including maintenance CapEx.
With that, I will turn it over to Michael. Michael?
