Saudi cement’s record clinker pile has not yet been tested. The test will fall hardest on those still adding stock.
Saudi cement producers ended October with a record 46.1 million tons of clinker in their yards, about ten months of sales. The total is a record. More telling is which way each company’s pile is moving. 
Clinker is half-made cement, produced by firing limestone and other raw materials in a kiln and then ground into the finished product.
When kilns run faster than customers buy, the unsold clinker piles up in the yard. That matters for Saudi companies’ profits.
The cost of making it isn’t charged against earnings straight away. It is parked in the stockpile as an asset, and reaches the income statement only when the clinker is sold, or when its value falls below cost and it is written down.
A growing pile can then make today’s results look better and leave the bill for later.
The two largest holders are moving in opposite directions. In the year to September, Southern Province Cement cut its clinker stock by 1.08 million tons, or 15%, most of it by March.
It has edged up since but remains below its 2025 peak. Yanbu Cement went the other way, adding 1.35 million tons, or 28.5%, and another 277,000 tons in October, enough to overtake Southern as the largest holder.
Measured against sales, the two piles are almost the same size: at the end of September, each equalled 18 to 19 months of sales. What separates them is direction. Southern has been working its pile down, while Yanbu is still building its own.
Elsewhere, producers divide along the same line over the same year to September. Umm Al-Qura, sitting on 22 months of sales, cut its stock by 6.6%.
Arabian Cement kept building, adding 15.5%, and so did Tabuk, which holds about the sector average, adding 16.7%. Najran held broadly steady.
For investors, the direction matters more than the size of the pile.
A producer working its stock down is selling clinker it has already paid to make, so that cost is moving out of its yard and into its results.
A producer still adding stock is carrying a growing cost, and has yet to learn whether it can sell that clinker for more than it cost to make.
The latest third-quarter results do not reveal which side a producer is on. Gross margin, the share of revenue left after the cost of what was sold, counts only the cement that left the yard.
Clinker still in stock doesn’t enter the calculation. Accordingly, a growing pile can sit behind a strong margin or a weak one.
Margin depends on the price and cost of each ton sold. A producer that keeps its kilns running while sales slow spreads its fixed costs over more tons and parks some of them in the stockpile, which can lift its margin.
If prices or sales fall, margins weaken, whatever the size of the pile.
Producers keep kilns running when sales slow for four reasons. Restarting a kiln wastes fuel and damages its lining. A full yard lets them meet a sudden rise in demand without losing customers. Burning fuel now avoids possible price rises later. Steady output spreads fixed costs, supporting reported profits.
The results bear that out. Yanbu, Arabian and Tabuk, all still adding to their stock, saw their gross margins fall by between 10 and 20 percentage points, as revenue dropped by 40%, 22% and 45%.
Umm Al-Qura, which has been cutting its stock, did no better: its margin fell 20.0 points as revenue dropped 18.0%.
Najran, whose stock barely moved, lost 14.7 points even though its revenue fell only 9.8%.
Knowing which way a company’s stockpile was moving would not have told you which way its margin went.
A record clinker pile, still untested
Southern, which has been cutting its stock, went the other way. Its gross margin rose 8.6 points to 21.4%.
Argaam’s results report puts the company’s nine-month improvement down to higher revenue and exports, and lower cost of goods sold.
A stockpile can hit profits in another way: through the inventory test. Accounting rules require stock to be valued at whichever is lower, what it cost to make or what it can be sold for.
If the selling price falls below the cost, the difference is written down and charged against that quarter’s profit.
At first sight, Southern has already faced that test. In its quarterly accounts, its inventory provision, the running total of write-downs, stood at SAR52.4 million at the end of September 2025.
By the end of December it was SAR99.3 million. In that quarter it made a gross loss of SAR89.8 million and a net loss of SAR92.8 million.
The audited accounts for 2025 tell a different story. Most of the jump was a correction to earlier years, not a new charge.
Southern had not booked an allowance of SAR41 million for spare parts on the old production line at Jazan, which management decided in 2023 to decommission.
Once that was added, the provision at the end of 2024 was restated to SAR93.5 million, and the charge for 2025 itself came to SAR5.8 million.
Whatever drove Southern’s fourth-quarter loss, it was not a large write-down in the value of its clinker.
This matters because the stockpile’s real cost has not yet been counted. Southern’s loss looked like a clinker write-down already taken, and it was not.
On present evidence, none of these six producers has visibly marked down the value of its clinker, so the test still lies ahead for all of them, most of all for those still adding stock.
The loss no broker forecast
The loss took analysts by surprise. All five broker forecasts for the quarter had expected a profit, of between SAR12.0 million and SAR21.9 million.
Southern attributed its 2025 loss to adjustments to work-in-process inventory, which is mostly clinker, and to raw materials, alongside higher production costs, plants running below capacity, and depreciation on the old lines at Jazan.
Since then, analysts have disagreed far more. For the third quarter of 2026, six forecasts ranged from a loss of SAR24.0 million to a profit of SAR30.2 million. Southern reported a profit of SAR5 million, near the middle of the range.
The other five producers carry provisions too, but they say little about clinker. At the end of September 2026, Yanbu’s provision equalled 9.2% of its gross inventory and Arabian’s 11.7%. At the end of June, Umm Al-Qura’s, Najran’s and Tabuk’s were each under 2%.
The quarterly figures do not say what each provision covers, but the way they move points to spare parts, the machinery components kept for maintenance, rather than clinker.
Yanbu’s provision fell by SAR30.6 million in the first half of 2026, broadly in step with a SAR36.5 million fall in its spare parts.
Arabian’s provision equals about half the value of its spare parts. Southern’s audited accounts show the same pattern: its provision is mostly for spare parts.
If that reading holds, none of these six producers has yet visibly marked down the value of its clinker. The test is still to come, and it will matter most for those still adding stock: Yanbu, Arabian and Tabuk.
What the full-year results will show
Does a big stockpile mean a loss is coming? Not necessarily. If the clinker is eventually sold for more than it cost to make, nothing has to be written down.
Whether a write-down comes depends on cement prices over the coming quarters, and nothing in these figures can tell us where they will go.
The figures also have limits. Companies report their own tonnage, and it can be corrected in one go: Al Jouf Cement’s stock fell by 757,000 tons in June, more than nine months of its sales. As Southern’s case shows, provisions can change at audit too.
The provision figures here are for the end of September 2026 for Yanbu and Arabian, and the end of June for the others. And six companies are a small sample.
The full-year 2026 results, due in the first quarter of 2027, will show where the test falls. Two things are worth watching: any fourth-quarter write-down of inventory at Yanbu, Arabian and Tabuk, the companies still adding stock, and whether their accounts begin to show clinker and spare parts separately.
