Thank you, Darron, and good morning to everybody on the call. Let's go ahead and do our normal full walk-through of the fourth quarter details. First, to reiterate the consolidated numbers, relative to last quarter, Q4's revenues were up 20% or $7 million moving from $35 million to $42 million. Adjusted EBITDA was down 27% or $1.2 million moving from $4.4 to $3.2 million. And as Darron mentioned just a bit ago, that $3.2 million in EBITDA does include $1.3 million of expenses associated with high-spec rig reactivations. Overall, the adjusted EBITDA margin moved from 13% to 8% for the quarter.
And now onto the segment details, starting with revenue. High Spec Rig revenue was up a solid 50% or $7 million, moving from $14 million to $22 million on the combined effect of an increase in period rig hours, along with an increase in composite rig rates. Specifically, revenue hours increased 43% or 12,900 hours, moving from 30,200 hours to 43,100 hours, partially on the addition of an average of 12 rigs in the quarter, bringing the Q4 average rig count to 42 rigs. Composite hourly rig rates also increased. They were up 5% quarter-over-quarter or $23 an hour, moving from $480 an hour to $503 per hour. Increased 24-hour work supported the higher rig rigs with 26% of our activity being 24-hour operations as compared to 20% for the third quarter.
In the Completions and Other Services segment, revenue saw a slight decrease of $300,000 moving to $18.6 million in Q4. This slight decrease was fully attributable to our Mallard Wireline business, which, as Darron detailed, on early year-end shutdown on budget's option and a COVID-related delay, along with ongoing pricing pressure. Here in the Mallard Wireline business, our revenues were down 7% sequentially, driven by a 6% decrease in composite pricing per stage, along with the stage count that was just slightly lower period-over-period. And finally, at our Processing Solutions segment revenues held flat at $1.2 million for the quarter.
Now moving on to segment level EBITDA and margins. Overall, segment level adjusted EBITDA just being before corporate G&A, saw a decrease of 13% or $1.1 million, moving down from $8.3 to $7.2 million in the fourth quarter, and an increase at the High Spec Rigs segment, offset primarily -- was offset primarily by the EBITDA decline in Completion and Other Services. On the margin front, consolidated segment margins, again before corporate G&A, were down from 24% versus 17%. G&A expense, as adjusted, was just up from flat at $4 million versus $3.9 million in Q3, which marks our third quarter at this new materially lower G&A run rate.
And now at the segment level, for High Spec Rigs, adjusted EBITDA was up 21% or $0.5 million, moving from $2.4 million to $2.9 million, with margins moving in the opposite direction down from 17% to 13% percent. I'll note here that adjusting out the $1.3 million of make-ready expenses seen in this segment would have resulted in an EBITDA increase of 75% sequentially, along with a margin increase to 19%. At the Completion and Other Services segment, adjusted EBITDA was down 28% or $1.4 million from $5 million to $3.6 million. Margins here were down from 27% to 19%. As noted earlier, the primary driver of this margin reduction was ongoing rate pressure at our Mallard Wireline business. This rate pressure has been with us for several quarters now. In the past, we've been able to at least partially offset this top line price pressure with reduction in [ frac and ] costs and labor efficiency gains. This quarter, however, we were not able to further squeeze costs and rate pressure at the top line translated into a one-for-one impact on margins. And finally, Processing Solutions adjusted EBITDA decreased 22% from $900,000 to $700,000, while segment margins moved down from 72% to 60%. And finally, on the net income line, for Q4, we reported a net loss of $6.7 million, a $1 million decrement to Q3's loss of $5.7 million. This change was in line with the sequential EBITDA change.
Now moving to the balance sheet. Net debt did show a modest increase in this quarter, moving up slightly from Q3's $2.4 million to a year-end balance of $26 million. This modest increase was driven by a $4 million working capital draw on the increased revenues, which was partially offset by this quarter's EBITDA. Our term debt balance was reduced another $2.5 million during the quarter, bringing the year-end balance to less than $18 million. In total, over the course of the entire year, we reduced our outstanding long-term debt by $16 million or nearly 50%, moving year-over-year from a balance of $33 million to, as I said, a year-end balance of just under $18 million.
CapEx, Q4 saw another quarter of near de minimis CapEx spend. As we noted earlier, we did see some significant spending in high-spec rigs on reactivation. However, we continued to adhere to our relatively high capitalization thresholds, resulting in little if any of that amount being capitalized. In total, we saw less than $600,000 of CapEx reported for Q4. Across all business lines, less than $200,000 of that $600,000 was on maintenance CapEx, with the remaining $400,000 largely driven by incremental real-time monitoring and data capturing systems, along with some expenses associated with the standup of a new human resource information system.
Liquidity, we ended the quarter with $16 million of liquidity, consisting of $13.2 million of capacity on our revolver and $2.8 million of cash. That's up $2 million from Q3's $14 million of liquidity. As of last quarter, the increase in liquidity was largely driven by an increase in borrowing base as our accounts receivable balances continue to [ lag ].
And finally, before I turn it back over to Darron, just a couple of housekeeping items on the balance sheet. Given the meaningful spread between our trading multiple and interest rates, we have long noted that it does not make much sense to keep any unnecessary fixed assets on our balance sheet. Specifically, this means that we do not have any strategic interest in maintaining material real estate holdings and effectively we'll lease rather than buy light-duty vehicles when the lease terms are favorable to us. This brings us to a couple of near-term action items. First, we've mentioned in the past that we've had an increase in unsolicited interest in sale-leaseback transactions on a couple of our field locations. And as a result, we have recently launched a formal sale-leaseback process on the largest of our facilities, the Milliken facility. To date, this process has been met with significant strong interest, and we look forward to continuing that process due through to its logic conclusion. Secondly, we have now fully rightsized our light-duty vehicle fleet to match our near-term outlook and expectations. And now having rightsized that fleet, we are restructuring the lease to match the current fleet size. These items taken together, when executed are expected to return more than $15 million of cash to the balance sheet with an implied interest rate of well down into the single digits.
Now I'll turn it back over to Darron.
