This Sunday stock review uses the completed October 23 U.S. regular session and SLB's September-quarter results. SLB reported on Friday, but a strong share-price close and a growing acquired business answer different questions. The operating test is how much of the Production Systems increase remains after the ChampionX comparison; the cash test is what remains after the investments in SLB's own free-cash-flow definition.
Separate acquisition growth from the operating base
SLB's Production Systems revenue was $4.000 billion in the quarter ended September 30, 2026, up from $3.474 billion a year earlier, a reported increase of about 15%. ChampionX contributed $950 million to that segment in the current quarter and $575 million in the prior-year quarter, which had only two months of ChampionX activity. SLB says Production Systems grew 5% year over year excluding the acquisition impact. The reported increase is real, but treating all of it as like-for-like demand would overstate the evidence.
SLB September-quarter release and reconciliation
The larger company reported $9.45 billion of revenue, $0.49 of GAAP earnings per share and $0.64 per share excluding charges and credits. That adjusted figure is SLB's non-GAAP measure, not a second GAAP result. Segment growth alone does not establish that operating margins or cash conversion improved across the entire business.
Follow the cash definition
SLB reported $1.510 billion of GAAP cash from operations for the September quarter. It then subtracts $485 million of capital expenditures, $114 million of APS investments and $83 million of capitalized exploration to arrive at $828 million of company-defined non-GAAP free cash flow. The bridge matters: ignoring APS and exploration would make the residual look larger than the figure SLB reports. This quarter's result does not pre-fund every future project or shareholder return.
For the next results, the useful checks are Production Systems growth on a comparable acquisition basis, the conversion of reported earnings into operating cash, and the capital needed to sustain that conversion. Commodity, customer-spending and integration conditions can change those results; Friday's quarter is evidence, not a guarantee.
The completed share chart
SLB closed October 23 at $53.06 on the completed daily history, up 7.08% from Thursday and 7.19% from the previous Friday's close. Nasdaq's dated regular close rounds to the same $53.06 at two-decimal precision. The independently calculated 20-, 50- and 200-day averages were $49.52, $52.47 and $51.26. The close was above all three, after reaching a corroborated Friday high of $53.45. That $53.45 is a dated session high, not a forecast.
A constructive follow-through would require a daily retest and close above a relevant reclaimed level, with $52.47 and $51.26 serving as separate prior-average references. Losing those levels on completed daily closes would weaken the repair case. The operating and cash questions remain even if the next share-price session extends Friday's move.
