Highlights In this report, we take a close look at corporate margins by analyzing their key drivers: The general level of economic activity, trends in labor costs and productivity, borrowing costs, tax rates, depreciation charges, the exchange rate, and corporate pricing power. The likely contraction of margins next year will be driven by a combination of factors: First and foremost, a slowdown in top-line growth and a decline in corporate pricing power. In the meantime, the tight labor market is putting upward pressure on wage growth despite a peak in productivity improvement. Input costs are also on the rise with PPI soaring, cutting into corporate profitability. Depreciation is already rising on the back of the recent recovery in capex. Interest expense has bottomed in the face of rising rates, and the potential healing of corporate balance sheets is leading to re-leveraging to raise capital for capex and buybacks. The US corporate tax rate is bound to increase based on news from Capitol Hill. The model above encapsulates all of these moving parts (Chart 1) and reiterates that the path of least resistance is lower for US corporate margins. S&P 500 operating margins are likely to contract in 2022. Feature Profits Have Rebounded S&P 500 earnings growth has rebounded vigorously from the pandemic low. Operating earnings-per-share stand 32% YoY above the January 2020 pre-pandemic high (Chart 2). Margins have also exceeded pre-pandemic levels of 11.7% reaching 14.4% in September (Chart 3). The basic story behind a rebound in profitability is well understood: Companies have cut costs aggressively, productivity has improved, lower interest rates have reduced debt servicing burdens, a weaker dollar has boosted overseas earnings, and corporate pricing power has strengthened. Gauging the direction of change for each of these various factors will help us assess whether profits can continue growing, and whether operating margins can continue expanding. Chart 1After An Impressive Surge, Margins Are Set To Decline Chart 2Profits Have Rebounded Vigorously Chart 3Margins Are Above Pre-pandemic High Sneak Preview: We expect profit margins to contract in 2022 NIPA Operating Margins vs S&P 500 Operating Margins The market tends to focus on S&P 500 earnings and these can be measured on a reported or operating basis, with the latter removing the effects of one-off charges. In order to better understand the path of S&P 500 margins, we aim to relate profits to the economic cycle; to do so, we analyze the data from the national income and product accounts (NIPA) because they are fully integrated with GDP and any related series. National non-financial after-tax profits without the inventory valuation adjustment (IVA) and the capital consumption adjustment (CCAdj)1 are conceptually closest to S&P 500 profits as they measure the after-tax worldwide earnings of US corporations. Fortunately, the S&P and equivalent national income measures of operating profits broadly track each other over the long run, although the S&P data display greater volatility. The NIPA profit margin series is 70% correlated with S&P 500 operating profit margins. While this level of correlation indicates that long-term trends in NIPA profits and S&P earnings are broadly similar, short-term annual and quarterly growth rates can differ dramatically. The Key Drivers Of Profitability A number of factors can influence the path of profits: The general level of economic activity, including trends in borrowing costs, tax rates, depreciation charges, the exchange rate, productivity, and corporate pricing power. It clearly would be most bullish if productivity had been the main driver because any future benefits from the other four sources will be limited. Interest rates will normalize at some point, and effective tax rates seem more likely to rise than fall from current levels, and we should hope for faster depreciation in line with increased capital spending. In addition, the downside in the dollar is constrained by the desire of other countries to maintain competitive exchange rates. Corporate pricing power is the sole mitigating factor against these cost pressures. In this report, we will methodically go through and assess the outlook for each of these profit drivers, and their cumulative effect on profit margins for the next year or so. Revenue Growth Is A Key To Margin Expansion The EBITD measure of domestic non-financial profits excludes the impact of changes in taxes, interest rates and depreciation charges and is thus the series that is most directly affected by the underlying economic cycle and by productivity. Moreover, because it covers only domestic profits, it is not overly influenced by exchange-rate movements. GDP growth and NIPA EBITD margin expansion move in tandem. The post-pandemic rebound in economic growth has underpinned margin recovery (Chart 4). However, real GDP forecasts have recently been cut from 6.5% to just under 6% for 2021, and to 4% in 2022 (Chart 5). Slower growth suggests that the pace of margin expansion will also slow. Chart 4EBITD Margins Usually Track GDP Chart 5GDP Growth Is Expected To Slow Cost Drivers Of Profits Labor Expense As Percentage Of Sales Has Been Falling Looking at the expense side of the NIPA Income Statement, we note that labor costs are singlehandedly the largest expense, hovering around 50% of sales, dwarfing all the other expense items (Chart 6). The NIPA EBITD margin allows us to gauge the effect of changes in labor costs on the bottom line. Chart 6Labor Costs Are The Largest Expense After the initial spike to 54% of sales at the beginning of the pandemic, explained by rapidly falling sales and an inability of companies to rapidly reduce employee numbers, labor costs as a percentage of sales have been reverting to historical levels. This is a curious phenomenon as wages have recently been on the rise: The number of open positions has been exceeding the number of job seekers by over a million, indicating that jobs are plentiful. As a result, the quit rate has exploded (Chart 7). To attract and retain workers, businesses have been raising compensation, leading to average weekly earnings rising by more than 5% year over year. As a result, wages-to-sales have been trending up (Chart 8). Chart 7Quit Rate Exploded Pushing Wages Up Chart 8Wages-to-Sales Have Been Trending Up If companies must pay more for labor, why has the labor expense as percentage of sales fallen? To answer this question, we will look at the selling prices over unit labor costs as a proxy for the EBITD margin (Chart 9) to examine the underlying profitability as a function of labor costs. However, since the beginning of the pandemic, this stable relationship has broken down, with selling prices falling over unit labor costs, while margins have been expanding. Digging deeper, we notice that NIPA sales prices have rebounded (Chart 10) due to a surge in inflation and a rise in a corporate pricing power (Chart 11), while unit labor costs dived. This can be attributed to a pandemic productivity surge (Chart 12), making it cheaper to produce each additional unit. Chart 9A Proxy For EBITD Margin Chart 10Sales Prices Are Up, Unit Labor Costs Are Down Chart 11US Corporate Power Is Waning Chart 12Productivity Has Peaked However, after rising for months, the ability of companies to raise prices further has been diminished by consumers’ income increasing slower than inflation, reducing their purchasing power. Improvements in productivity have also peaked and are unlikely to propel margins higher. Input Costs Are Soaring While cost of goods sold (COGS) is not one of the lines in the NIPA income statement, we would be remiss not to mention that input costs have been on the rise. The most recent reading in PPI was up 8.3% YoY (Chart 13). The price of oil has been surging as well. An increase in the cost of materials definitely has an adverse effect on corporate margins. We will quantify the effects of the year-on-year percentage of PPI on margins later in this report. Chart 13Input Prices Have Soared Other Drivers Of Profitability: Depreciation, Interest And Taxes Switching gears to other costs, interest, taxes, and depreciation expenses are likely to increase going forward. Capex Is Rising, So Will Depreciation Expense Depreciation expense is the second largest expense in the cost structure, constituting some 15% of sales. Between mid-2009 and mid-2012, depreciation charges fell sharply, curtailed by weak investment growth during the Global Financial Crisis (GFC) economic downturn. Similarly, the same story unfolded during the 2015 manufacturing slowdown, and the pandemic-induced recession (Chart 14). Today, growth in US domestic fixed investment has rebounded at rates comparable to the 2000 and 2010 recoveries. The trend will continue: According to the Philly Fed Manufacturing Survey, capex intentions have been rising (Chart 15). As a result, depreciation expense is set to climb, cutting into margins and earnings. Chart 14Capex Surge Will Lead To Higher Depreciation Chart 15More Capex Is Under Way Interest Costs Set To Increase With Rising Rates Interest charges are small compared to other expenses, never rising above 5% of sales. There has been quite a lot of variability in interest charges in recent years, reflecting swings in both interest rates and the level of corporate borrowing (Chart 16). Falling interest costs provided a boost to profits between 2008 and 2010, as well as during the trade war and the pandemic. Also, corporations have been de-leveraging, but this trend is about to turn: As the corporate sector heals, it is likely to re-leverage, whether to finance capex or buybacks. With interest rates set to rise, interest costs are likely to become a drag on profits (Chart 17). Chart 16Higher Rates And Corporate Re-Leveraging Will Push Interest Costs Up Chart 17Corporate Debt Has Bottomed Effective Tax Rates Are Likely To Increase Effective tax rates have fallen from about 18% in 2014-2017 to 12% in January 2018 because of the Trump Administration’s tax reform and remain low by historical standards (Chart 18). Meanwhile, taxes paid have also been hit by the 2020 downturn thanks to temporary tax breaks, and have not yet rebounded to pre-pandemic levels, thereby aiding margin expansion. However, given the Biden Administration’s push to increase the US corporate tax rate and eliminate loopholes, chances are that tax expenses will rise. Chart 18Effective Tax Rates Are Low By Historical Standards Overseas Profits So far, we have focused on the domestic drivers of changes in margins. Yet for many US corporations, especially the ones in the S&P 500, overseas profits are a key source of profits. Many industries derive a substantial share of sales from abroad, and for Technology, this number stands as high as 58%. Historically, overseas profits have been a tremendous source of growth (Chart 19) thanks to rising exposure to fast-growing emerging economies, a weaker dollar, and the transfer of operations to low-tax regimes. However, recently this trend has turned due to closing loopholes allowing companies to locate headquarters in lower tax regime jurisdictions, tax reform, foreign profits amnesty, and unified global pressure to tax US multinationals. Onshoring of manufacturing production is another emerging trend that is likely to improve the efficiency of supply chains but will add to production expenses, chipping away at corporate profitability. The US dollar has been weakening during the pandemic, giving a boost to profits thanks to both lower prices of the American goods and translation effects (Chart 20). Chart 19Overseas Profits Are Trending Down Chart 20USD TRW Is Strengthening Hence, we conclude that the share of overseas profits is unlikely to change and is not going to become an engine for profit growth for US corporations. Where Next For Profits? The clear implication from the above analysis is that profits have ceased to benefit from earlier benign trends in depreciation charges, interest costs, and tax rates. Looking ahead, these factors, are destined to become modest headwinds for profit growth. Sales growth is also likely to slow as GDP growth returns to trend, with overseas profits less of a source of growth. And importantly, productivity growth and pricing power have peaked and turned, depriving the economy of its key drivers of margin expansion. S&P 500 The obvious question is how all the factors affecting NIPA margins translate into the forecast for change in S&P 500 operating margins. S&P 500 margins are subject to the same profit drivers as the NIPA accounts. In order to forecast the effect of these factors on the year-on-year changes in operating margins, we have built a simple regression model that uses year-on-year changes in average hourly earnings (AHE) to capture the cost of labor; high-yield option-adjusted spreads (OAS) to capture the cost of borrowing; year-on-year PPI as a change in cost of input materials; the trade-weighted USD as an indicator capturing change in foreign profits; and, lastly, the BCA pricing power indicator to measure companies’ ability to pass on these costs to their customers (Table 1). Table 1Regression To Predict Operating Margins YoY% The model forecast of margin growth peaked in August 2021 and is about to slow into the balance of the year (Chart 21). Margins will contract outright in December 2021-January 2022. The growth rate for margins in January 2022 is -65% year on year. In January 2021, operating margins were 7.2%. Incorporating a negative year-on-year growth rate, we arrive at margins of only 2.6%, which is certainly very low. The caveat here is that our objective is to predict the direction of change as opposed to working out a point estimate of future margins. In other words, there is a wide confidence interval around any forecast of earnings given the unpredictability of movements in the exchange rate, productivity and the general level of economic activity. However, our assumptions are conservative, and the model clearly points to a margin contraction in 2022. Chart 21After An Impressive Surge, Margins Are Set To Decline And lastly, why will margins contract? What is the main culprit that would make things worse? The answer is an increase in input and labor costs (PPI and AHE), both of which are no longer being offset by a corporate pricing power: The ability of corporations to pass on their costs to customers has diminished, and margins are going to take a hit (Chart 22 & Table 2). Chart 22Increase In Costs Is No Longer Offset By Pricing Power Table 2Contributions To Margins Growth Bottom Line Earnings growth and profit margins are of paramount importance to the performance of equities – as we wrote in a report in August, the key driver of returns has shifted from multiple expansion to earnings growth. Despite the recent pullback, the S&P 500, trading at 20.5x forward multiples, is still expensive. Our analysis shows that S&P 500 operating margins are likely to contract in 2022 because of rising wages, a slowdown in productivity, increases in interest and depreciation expenses, and potential tax hikes. On the revenue side, US GDP growth is slowing, and corporate pricing power is waning, making it difficult to pass on rising costs to customers. Impending margin contraction does not bode well for the strong performance of US equities in the year ahead.

The inventory valuation adjustment (IVA) and the capital consumption adjustment (CCAdj) are used to adjust before-tax profits to NIPA asset valuation concepts. The IVA adjusts inventories to a current-cost basis, which is similar to valuation of inventory withdrawals on a last-in/first-out basis. The CCAdj adjusts tax-reported depreciation to the NIPA concept of economic depreciation (or “consumption of fixed capital”), which values fixed assets at current cost and uses consistent depreciation profiles based on used asset prices.
