The wide quarterly swings in gross margin—from 3.7% in Q4 2024 to 12.9% in Q1 2025—are characteristic of percentage-of-completion accounting, where cumulative catch-up adjustments can distort a single period. The normalized operating margin, hovering around 12% in most quarters, appears to be the truer measure of earning power, as it smooths out the noise from program estimate changes. Investors should focus on the trend in operating margin excluding these adjustments, as the reported figures may overstate or understate the underlying profitability in any given quarter.

The stability of ROIC around 7% contrasts with the volatile ROE, which ranged from 5.7% to 28.1% over the same period. The ROE swings are largely driven by the thin equity base and leverage, not by changes in operating performance. The fact that ROIC has not expanded despite record backlog and revenue growth suggests that the company is investing heavily in working capital and fixed assets to support the F-35 ramp, which may be diluting returns. This warrants monitoring: if ROIC remains flat while revenue grows, it implies that incremental capital is not generating incremental returns, a potential sign of diminishing returns on growth.

The CCC has oscillated between 46 and 88 days over the past ten quarters, with DSO ranging from 49 to 88 days. The Q2 2026 improvement to 46 days is notable, but it follows a quarter where DSO was 86 days, suggesting that the company's working capital is heavily influenced by the timing of large contract payments. The DPO has remained relatively stable around 20 days, indicating that Lockheed Martin does not have significant leverage over its suppliers, likely due to the specialized nature of its supply chain. Investors should not read too much into a single quarter's CCC, but the trend suggests that cash flow will remain lumpy as program milestones are met.

The deleveraging trend is positive, but the absolute level of debt remains high relative to the equity base, which is thin due to aggressive share repurchases. Interest coverage of 9.32x in Q2 2026 is up from 2.52x in Q2 2025, reflecting both higher operating income and lower debt levels. However, the D/E ratio of 2.34 is still more than three times that of RTX and GD, suggesting that Lockheed Martin is more levered than its peers. This leverage is partly a result of a shareholder-first capital allocation strategy, but it also increases sensitivity to interest rate changes and any downturn in defense spending. The improvement in coverage is reassuring, but the structural leverage remains a key risk.

The improvement in the current ratio is a positive sign, but a ratio of 1.19 is still low for an industrial company, indicating that Lockheed Martin relies heavily on operating cash flow to meet short-term obligations. The quick ratio of 1.01 suggests that inventory is not a major liquidity concern, but the company's heavy reliance on government contracts means that any delay in payments could strain liquidity. The $3.8B cash balance provides some cushion, but it is small relative to the $20.5B in total debt. While the liquidity position appears adequate under normal conditions, it could be vulnerable to a severe disruption in government funding or a major program charge.
