Question · Q1 2025

Scott Mikus from Melius Research questioned the decision to reaffirm guidance despite a strong Q1 EPS beat, asking if core fundamentals are expected to deteriorate or if the guidance is simply conservative.

Answer

CFO Chris Cage asserted that core business fundamentals are not a concern and remain strong.

Question · Q4 2024

Scott Mikus questioned the 2025 EPS guidance, noting that after adjusting for 2024's one-time charges, it implies minimal underlying growth, and asked if this reflected conservatism.

Answer

CFO Chris Cage acknowledged the observation but cited several factors: the need for investment flexibility in a "pivot year," expected headwinds from higher interest rates on refinanced debt, a slightly higher tax rate, and the fact that 2024 benefited from an unusually strong year for program performance (EACs) that may not repeat at the same level.

Scott Mikus's questions to L3HARRIS TECHNOLOGIES, INC. /DE/ (LHX) leadership

Question · Q3 2025

Scott Mikus questioned the decline in L3Harris's IRAD spend as a percentage of sales from 3.5% in 2022 to 2.4% in 2024, asking if this spend is expected to increase in 2026 given the administration's push for contractors to invest more.

Answer

Chairman and CEO Christopher Kubasik clarified that L3Harris views R&D broadly, encompassing IRAD, CRAD, Shield Capital, and other strategic investments, rather than solely as a percentage of revenue. He explained that once new markets are established and portfolios mature into production, the need for initial R&D investment shifts, and current results demonstrate that past investments in IRAD, CapEx, and acquisitions have successfully positioned the company for future growth.

Question · Q3 2025

Scott Mikus asked about Hexcel's approach to Long-Term Agreement (LTA) negotiations, specifically whether the company aims to retain a larger share of productivity benefits as agreements come up for renewal.

Answer

CEO Tom Gentile and CFO Patrick Winterlich explained that while contracts include inflation and volume protections, productivity gains are often shared with customers since their cooperation is required for process changes.

Question · Q1 2025

Scott Mikus of Melius Research asked if Hexcel had approached its major customers, Boeing and Airbus, about repricing long-term agreements to offset inflation and production volatility. He also questioned if the Austrian facility could be repurposed for European defense programs if a sale is not completed.

Answer

Chairman, CEO and President Tom Gentile explained that they negotiate pricing with Boeing as shorter-term contracts expire. For the long-term A350 contract with Airbus, which runs to 2030, the focus is on joint productivity programs to share cost savings rather than repricing. He stated the Austrian facility is tailored for industrial production (wind, recreation) and is not suitable for producing aerospace-grade materials for defense programs.
