Electrical distributors are reporting revenue growth in an environment where copper prices have risen sharply. That creates an important analytical problem: a distributor’s revenue can increase even when it sells the same physical volume of wire and cable. The reported number is real, but it does not tell the whole story.
This distinction matters to distributors, manufacturers, investors, lenders, boards, and industry analysts. If commodity-driven price increases are mistaken for volume or market growth, you may overstate underlying demand, misread competitive performance, and make poor planning decisions.
Expense ratios also need context
Higher selling prices can make operating expenses look better as a percentage of sales without an improvement in productivity. Selling the same amount of wire at a higher price does not necessarily create more orders, warehouse work, or deliveries. An improving expense ratio may therefore partly reflect higher prices rather than greater efficiency.
The effect can reverse
As copper-price inflation slows, its contribution to reported sales growth can diminish. If prices fall, revenue can decline even when physical volume is unchanged. Expense ratios can also look worse without any increase in spending.
The assumptions require judgmentÂ
The arithmetic is not the difficult part. The assumptions are. A distributor may not pass through the full copper increase immediately. Inventory purchased before the price increase may be sold later. Competitive conditions may limit price recovery. The copper content of different wire products may vary. Customer contracts and quoting practices may delay recognition.
The calculator therefore includes a pass-through assumption. A 100% setting represents full and immediate pass-through. Lower settings provide a more conservative sensitivity case. Users should replace the industry-average wire mix and margin with company-specific inputs whenever those figures are available.
NAED members can test the estimate using their own assumptions in the companion web calculator. It operates locally in the browser and does not require a company name, revenue figure, login, or email address.
Copper-price inflation does not invalidate reported revenue growth. It makes revenue growth an incomplete measure of underlying business momentum. An effective analysis requires you to separate commodity-driven price effects before drawing conclusions about volume, market share, end-market exposure, or operating performance.
The adjustment is not meant to be a perfect accounting restatement. It is a transparent analytical tool for asking how much reported growth reflects more business and how much reflects higher prices on business already being done. With this information, you can start more effective leadership conversations about what is working for your business and why.
