EV demand and margin compression
Margin Compression Masks Underlying Strain
According to recent quarterly filings, ATS's operating margin fell to 4.3% in 2027Q1 from 10.3% in 2026Q2, while gross margin held near 27.4%, indicating cost absorption issues.
The gap between gross margin and operating margin widened to over 23 percentage points in 2027Q1, suggesting that SG&A and other fixed costs are consuming an outsized share of revenue as growth decelerates. The 2025Q4 quarter, with a gross margin of 10.8% and an operating loss, appears to reflect a project execution failure that may have lingering effects. Investors should monitor whether the recent SG&A spike to 23.1% of revenue is a temporary integration cost or a structural shift in the cost base.
Returns on Capital Remain Subdued
Based on reported figures, ATS's ROIC has hovered below 2% for most of the past ten quarters, with 2027Q1 at 0.8%, while ROE turned negative, suggesting capital deployment is not yet generating adequate returns.
Despite a 17.4% revenue growth rate on a TTM basis, the company's return on invested capital has not improved, indicating that acquisitions and organic investments are not yet translating into profitability. The low ROE of 4.1% on a TTM basis, combined with a debt/equity of 0.81, implies that leverage is not amplifying shareholder returns. This may reflect early-stage integration costs or margin pressure from fixed-price contracts, and investors should monitor whether returns improve as the revenue growth matures.
Working Capital Cycle Lengthens
As reported in financial statements, ATS's cash conversion cycle extended to 74 days in 2027Q1 from 109 days a year earlier, driven by a DSO of 131 days, indicating slower collections on project-based revenue.
The DSO has remained elevated above 130 days in recent quarters, which appears consistent with percentage-of-completion accounting and large contract milestones, but it also suggests potential collection risk. The DPO of 111 days provides some offset, but the net working capital drag is evident in the volatile cash flow from operations, which swung from $155.8M in 2026Q1 to -$10.3M in 2027Q1. This lengthening cycle may indicate that customers are delaying payments or that project billing is becoming less efficient, warranting close monitoring.
Leverage Eases but Debt Service Tightens
According to recent balance sheet data, ATS's debt/equity improved to 0.77 in 2027Q1 from 0.99 a year earlier, yet interest coverage fell to 1.16x, indicating that debt service is becoming less comfortable.
While the absolute debt level has declined, the interest coverage ratio of 1.16x in 2027Q1 is barely above the breakeven point, and the D/EBITDA ratio of 19.84x is extremely high, suggesting that EBITDA has contracted sharply relative to debt. The 2025Q4 quarter saw negative interest coverage, and the recent trend shows volatility in coverage, which may indicate that the company is vulnerable to further margin compression. Investors should monitor whether the deleveraging continues and whether operating earnings stabilize to support debt service.
Liquidity Buffer Thins as Cash Declines
Based on quarterly filings, ATS's cash balance fell to $198.9M in 2027Q1 from $285.0M in 2026Q4, while the current ratio held at 1.63, suggesting a reduced cash cushion despite stable short-term coverage.
The current ratio of 1.63 and quick ratio of 1.33 indicate that current assets cover current liabilities, but the declining cash balance and negative free cash flow of -$26.0M in 2027Q1 point to a tightening liquidity position. The company's reliance on working capital swings, as seen in the volatile cash conversion cycle, could strain liquidity if project delays or cost overruns persist. Under a severe stress scenario, the thin cash buffer may force reliance on credit facilities, which could be costly given the already elevated leverage.
Misapplied EV/EBITDA Multiple
The most commonly misapplied ratio for ATS is EV/EBITDA, which at 10.15x appears attractive, but given the company's project-based revenue and volatile EBITDA, this multiple obscures the true earnings power.
EBITDA for ATS is heavily influenced by percentage-of-completion accounting and can swing dramatically quarter to quarter, as seen in the 2025Q4 operating loss. Using EV/EBITDA without adjusting for the lumpy nature of project revenue and the high D/EBITDA ratio of 19.84x in 2027Q1 can mislead investors into thinking the company is undervalued. A more appropriate metric would be EV/order backlog or EV/normalized earnings, which better capture the long-cycle nature of the business and the potential for margin recovery.
