Littelfuse (LFUS) has opened 2026 with Q1 revenue of US$657.0 million and basic EPS of US$3.00, alongside net income of US$75.1 million, while trailing 12 month figures still show a net loss of US$40.1 million and basic EPS of US$1.61 loss. Over recent quarters the company has seen revenue move from US$554.3 million in Q1 2025 to US$656.9 million in Q1 2026, with basic EPS shifting from US$1.76 to US$3.00 and quarterly net income changing from US$43.6 million to US$75.1 million. This sets up a story of improving quarterly profitability against a still negative trailing earnings base that keeps the focus squarely on margin resilience.

With the headline numbers in place, the next step is to see how this mix of quarterly profit and trailing losses lines up with the prevailing narratives around Littelfuse's growth prospects and risk profile.

TTM still in loss despite Q1 profit

• Over the last twelve months, Littelfuse booked revenue of US$2.5b but a net loss of US$40.1 million, so the Q1 2026 profit of US$75.1 million has not yet offset earlier losses in the period.
• Consensus narrative points to earnings reaching about US$396.8 million by around April 2029, yet the current trailing loss and TTM basic EPS of a US$1.61 loss highlight how much of that path still sits in front of the bullish expectations.
  • Analysts in the consensus view expect margins to move from a loss position of about 3.0% today to 13.0% in three years. The recent twelve month net loss shows that margin shift is not visible in historical data yet.
  • Forecast revenue growth of about 8.5% a year compares with trailing growth of roughly 6.6% a year, so investors are being asked to assume faster growth than what the last year of reported numbers reflects.

Volatile EPS track before Q1 rebound

• Basic EPS moved from a US$2.09 loss in Q4 2024 to US$1.76 in Q1 2025, then to US$2.32, US$2.80 and a US$9.72 loss in Q4 2025, before reaching about US$3.00 in Q1 2026, so reported EPS has swung between profits and losses across these six quarters.
• Bulls argue that operational improvements and acquisitions can support higher and more stable earnings, and the recent EPS path partly supports and partly challenges that story.
  • The bullish narrative looks for EPS to reach about US$16.43 by around July 2028, compared with the current trailing twelve month basic EPS loss of US$1.61, so the recent quarter is only an early step against a much larger earnings jump assumed in those forecasts.
  • Forecast margin expansion from roughly 4.3% to 14.2% in the bullish case is being inferred alongside revenue growth of about 8.4% a year, while the history of alternating profit and loss quarters shows that margins have not yet settled into the kind of smooth trend those projections assume.

On this kind of earnings swing, bulls say the real story is how quickly margins can settle at higher levels, not just one good quarter 🐂 Littelfuse Bull Case

Premium valuation with unprofitable TTM

• The stock trades at US$441.67 against a cited DCF fair value of about US$336.29 and a P/S of 4.5x versus 2.6x for the US Electronic industry and 3.1x for peers, while the business is still loss making over the last twelve months.
• Bears focus on that mix of premium pricing and trailing losses to argue the bar is high for the company to meet expectations.
  • Losses have grown by about 26.7% a year over the past five years and TTM net income is a US$40.1 million loss, so the premium to the DCF fair value is being supported by forecasts rather than recent profitability.
  • Projected revenue growth of 6.6% a year is below the US market’s 11.3% a year, which critics see as a mismatch with the current P/S premium relative to the industry and peer averages.
