ESCO Technologies just reported the quarter that explains why the stock has climbed so far so fast, and then announced the deal that explains why the market is willing to pay so much for what comes next. In fiscal Q3 2026, the quarter that ended June 30, 2026 under ESCO's September fiscal calendar, sales rose 14.4% to $339.0 million and diluted earnings per share from continuing operations climbed to $1.26 from $0.96 a year earlier. Backlog reached $1,540.5 million, up roughly $407 million from the prior fiscal year end, and nine month operating cash flow more than doubled to $193.4 million. The shares trade at $275.62, against a 52 week range of $192.05 to $362.15, giving the company a market capitalization of about $7.14 billion and a trailing price to earnings ratio of 53.2x that compresses to 29.9x on forward estimates. The dividend yield is a token 0.11%. That gap between trailing and forward multiples is essentially the price of the Megger deal.
What changed is scale. On April 15, 2026 ESCO signed a definitive agreement to acquire Megger, the utility test and measurement business of TBG AG, for roughly $2.35 billion, a mix of about $900 million in cash and $1.4 billion of ESCO equity, with closing expected in the first quarter of fiscal 2027. Megger is roughly the size of ESCO's entire current Utility Solutions Group several times over in enterprise value terms, and it lands in a segment where ESCO's own Doble franchise is already growing double digits on the strength of grid modernization spending. The strategic logic is coherent: ESCO is assembling a utility testing and monitoring platform around an aging, increasingly stressed electric grid, while its Aerospace and Defense segment rides a navy and maritime backlog that has rarely looked better.
The strongest evidence the operating story is real sits in the segment numbers. Aerospace and Defense generated a 30.0% EBIT margin in the quarter, with navy revenues up $22.3 million year over year and Maritime contributing $22.7 million of growth. Utility Solutions grew 8.2% with Doble adding $12.9 million even as the NRG renewables business shrank, and nine month orders across the company reached $1,344.9 million against $938.0 million of sales, a book to bill of 1.43.
The counterargument is equally straightforward. Q3 orders of $409.5 million were down sharply from the $749.1 million booked a year ago, and even after stripping out the $364.2 million of acquired backlog that inflated the prior year comparison, the Aerospace and Defense order rate cooled. The Megger deal adds approximately $800 million or more of new debt and roughly 16 to 20% share dilution at the current price, and integration of a $2.35 billion acquisition is where most industrial roll up stories earn or lose their premium. Meanwhile the 53.2x trailing multiple leaves little margin for execution slips in the base business.
The variables that decide this stock from here are the pace at which the $1.54 billion backlog converts to revenue and margin, whether Megger closes on schedule in the December quarter and integrates without margin erosion, and whether Doble's growth can absorb NRG's renewable weakness for several more quarters. On valuation, the forward multiple implies the market already expects the combined company to earn roughly $9 per share within about a year of closing. The rest of this report examines whether that expectation is earned by the evidence in the filing.
