WillScot shares fell 2.8% to $25.80 on Aug. 6. The filing offers a less tidy explanation than the price move: sales grew, but the operating engine kept less of each dollar.
Revenue rose 3.9% to $612.2 million in the three months ended June 30, 2026, while operating income fell 7.4% to $117.5 million. Operating margin dropped to 19.2% from 21.5%. Net income barely changed, and diluted EPS stayed at $0.26, helped in part by a smaller share count.
That makes the central tension fairly concrete. WillScot is adding business and investing in rental equipment, but the latest period produced less operating profit. Gross margin moved only slightly, from 50.3% to 50.0%, so the sharper pressure came below gross profit.
Management itemized the squeeze this way:
"The decrease was driven by increased cost of leasing of $20.7 million, increased SG&A of $12.5 million, and decreased new and rental unit sales gross profit of $9.7 million."

The plain-English version is that the additional sales did not cover the higher costs attached to running and selling the business. The result was $9.4 million less operating income on $23.1 million more revenue. Growth, in other words, arrived with less operating leverage, meaning less profit from each incremental dollar of sales.
Demand is not moving uniformly across the fleet. Modular-space units on rent declined as non-residential construction starts weakened, although management said large complex projects partly offset that pressure. Portable-storage average units on rent fell 7,244, or 6.7%, in the three months, driven by lower demand.
The company is still putting capital behind capacity. Net capex increased 43.1% to $113.7 million in the three months, primarily because of rental-equipment spending. Management described the broader investment as a response to large-project demand:
"The decrease was partially offset by a $66.2 million increase in the purchase of rental equipment and refurbishments during the six months ended June 30, 2026 as a result of increased investments in refurbishments and new fleet investments in FLEX and complex units to provide capacity to deliver on large project demand."

That is the balance-sheet stake in the filing. WillScot is spending to have more equipment available for projects while some existing rental categories are seeing fewer units on rent. Cash rose to $18.2 million from $12.8 million, but the latest three months also carried $113.7 million of net capex, and free-cash-flow margin declined 5.2 percentage points.
The company’s own annual results show the backdrop: revenue slipped 4.8% in 2025, while operating margin fell to 8.0% from 11.0% in 2024. The latest three-month numbers show sales growth returning, but not yet at the operating-margin line.
The unresolved piece is whether large complex projects can absorb the new fleet investment while weaker portable-storage demand persists. WillScot’s next quarterly report will put that question against the reported 19.2% operating margin and the 7,244-unit portable-storage decline.
