EnerSys (NYSE: ENS) reported fiscal first-quarter 2027 net sales of $935.6 million, up 4.8% from $893.0 million, while GAAP diluted EPS rose 112% to $3.09 from $1.46. Earnings grew much faster than revenue as gross margin expanded, operating expenses declined, and the quarter benefited from IRC 45X credits and $30.9 million of tariff refunds. Operating cash flow reached $230.2 million, supported by higher earnings and a U.S. federal tax refund.

Core financial results

Revenue growth was driven by a 3% increase in pricing, a 1% favorable contribution from foreign currency translation, and a 1% increase in organic volume. Profitability improved more sharply: gross profit increased by about 24%, operating earnings rose approximately 75%, and net earnings more than doubled.

The following figures cover the quarter ended July 5, 2026. Dollar amounts are in millions except per-share data.

Business and segment performance

EnerSys said improved volumes and favorable price and mix in its NIS and PPS segments more than offset continued softness in IMS. The principal pressure remained material handling, where the expected demand recovery has taken longer to develop.

By end market, data centers, communications, and aerospace and defense generated sales growth and supported margin expansion. Management also pointed to early recovery in transportation, but material handling remains the main area where a more meaningful improvement has yet to appear.

The revenue mix indicates that pricing remained the largest contributor to the quarter’s 4.8% growth, while organic volume added only 1%. A broader volume recovery would therefore be important for the company’s plan to shift from margin-led earnings growth in the first half of fiscal 2027 toward faster revenue growth later in the year.

Margin expansion outpaced sales growth, but credits and refunds mattered

GAAP gross margin increased 510 basis points to 33.5%. Excluding IRC 45X benefits, gross margin was 28.5%, still 440 basis points above the prior-year period. This indicates that most of the year-over-year margin expansion was not solely attributable to the manufacturing production credits.

Operating expenses also fell to $151.3 million from $160.8 million despite higher sales. As a result, GAAP operating margin increased to approximately 16.2% from 9.7%. Restructuring and other exit charges, however, rose to $10.7 million from $5.9 million.

Investors should still distinguish reported earnings from the company’s underlying measures. Adjusted diluted EPS excluding IRC 45X benefits was $2.41, up 92%. After also excluding the quarter’s one-time tariff refunds, adjusted diluted EPS was $1.78, up 42%. The latter measure shows that underlying earnings improved, but it also demonstrates how much the credits and refunds contributed to the reported result.

GAAP net earnings included $21.2 million, or $0.57 per diluted share, of unfavorable highlighted items. The comparable quarter included $30.1 million, or $0.77 per share, so a smaller adjustment-related drag also contributed to the year-over-year increase in GAAP EPS.

Cash flow, leverage, and capital allocation

Operating cash flow rose to $230.2 million, while free cash flow moved from a $32.1 million outflow to a $217.8 million inflow. EnerSys attributed the improvement to higher earnings and receipt of a U.S. federal tax refund. Free cash flow also reflected lower capital expenditures of $12.4 million, compared with $33.0 million a year earlier.

Cash and cash equivalents stood at $530.7 million at quarter-end, while net debt was $521.5 million. The net leverage ratio declined to 0.8 times EBITDA from 1.6 times in the prior-year period due to lower debt, higher earnings, and the tax refund.

EnerSys returned $59.6 million to shareholders during the quarter, consisting of $50.0 million of share repurchases and $9.6 million of dividend payments. The board subsequently increased the quarterly dividend by 10% to $0.2875 per share for the second quarter of fiscal 2027.

Guidance

EnerSys expects second-quarter revenue to exceed the first-quarter level, with continued demand from data centers, communications, and aerospace and defense, along with an early transportation recovery. The outlook also assumes another sizable contribution from IRC 45X benefits.

Management expects margin expansion to remain the main earnings driver during the first half of fiscal 2027. It expects the emphasis to shift toward stronger revenue growth near the end of the fiscal year, supported by a material handling recovery and continued momentum in other core markets.

Risks investors should monitor

• Delayed material handling recovery: IMS remained soft, and the company’s expectation for stronger late-year revenue growth partly depends on material handling demand improving.
• Earnings comparability: IRC 45X benefits and the one-time tariff refunds materially increased the quarter’s adjusted EPS. Changes in policy or the absence of similar refunds could affect future comparisons.
• Cash flow normalization: First-quarter cash generation benefited from a federal tax refund and lower capital expenditures. These factors may make the quarter’s free cash flow conversion difficult to repeat at the same level.
• Reliance on pricing before broader volume growth: Pricing contributed 3% to sales growth compared with 1% from organic volume. Slower pricing benefits without a stronger volume recovery could pressure revenue growth.

Summary

EnerSys began fiscal 2027 with moderate sales growth but substantially higher margins, earnings, and cash flow. NIS and PPS performance, pricing, cost control, IRC 45X credits, and tariff refunds outweighed continued weakness in material handling. The next areas to monitor are whether margin improvement persists without one-time benefits, whether material handling demand recovers, and whether management’s expected shift toward faster late-year revenue growth takes hold.
