Cash fell 71.3%. That is the oddest number in Exponent's latest filing, especially because the business also grew revenue 20.9% to $171.6 million over the three months ended July 3, 2026.
The income statement looks much cleaner than the balance sheet. Operating income jumped 63.1% to $28.0 million, lifting operating margin to 16.3% from 12.1%. Net income rose only 10.7%, to $29.4 million, and diluted earnings per share increased 15.4% to $0.60 as the diluted share count fell 4.9%.
The cash balance moved from $231.8 million to $66.6 million. Accounts receivable rose 27.8% year over year, and free-cash-flow margin fell 6.1 percentage points on a comparable basis. Exponent does not disclose in the supplied filing receipts what caused the cash decline, so the important fact is the mismatch itself: more reported work, more money owed to the company, and much less cash on hand.
The filing also gives two clues about why the bottom line did not keep pace with operating income. The first concerns deferred compensation, an expense tied to the value of assets associated with employee plans.
"During the second quarter of 2026, deferred compensation expense decreased by $5,180,000, with a corresponding decrease to other income, net, as compared to the same period last year, due to the change in value of assets associated with our deferred compensation plans."

That is not a consulting-project margin issue. It is an investment-linked accounting swing below operating income, and the corresponding decrease in other income offset the change's effect on net income.
Bonus expense moved in the other direction. Exponent said the increase reflected a larger bonus pool, which is set at 33% of a defined measure of pretax income.
"During the second quarter of 2026, bonus expense increased by $2,990,000 due to a corresponding increase in our bonus pool which is 33% of income before income taxes, interest income, bonus expense, and stock-based compensation."

Together, those disclosures help explain the earnings shape: operating profit expanded sharply, but compensation-related items and other income kept net income growth closer to 11%. The company also reported that capital expenditures rose 5.0% year over year, with investment directed toward corporate infrastructure. That is a disclosed use of resources, not an explanation for the cash balance.
There is a useful historical wrinkle. Exponent's latest full-year results showed revenue of $582.0 million, up 4.2%, with a 20.6% operating margin. The latest three-month period is therefore running at a much faster revenue pace, but its operating margin remains below that annual level. Growth arrived with a stronger operating line, while cash conversion became the harder number to read.
At the latest close, Exponent's shares were $66.31, down 0.9% on Aug. 6. The company has a $3.4 billion market capitalization and trades at 32.1 times earnings, figures that put attention on whether the current growth rate and cash profile persist without requiring a tidy explanation from accounting footnotes.
The unresolved item for Exponent's next quarterly report is simple: what explains the 71.3% cash decline alongside the 27.8% increase in accounts receivable?
