Honeywell's Board Recommends 'FOR' Proposal 3 Proposal 3 Approval of independent accountants The Audit Committee recommends approval of its appointment of Deloitte & Touche LLP (Deloitte) as independent accountants for Honeywell for 2026 The Audit Committee, and Honeywell's Board, believe that the continued retention of Deloitte is in the best interests of the Company and its shareowners The Audit Committee concluded that Deloitte's provision of non-audit services, as detailed in the 2026 Proxy Statement (page 108), is compatible with Deloitte's independence 2026 Annual Meeting - Shareowner Engagement

Honeywell's Board Recommends 'FOR' Proposal 4 Proposal 4 REVERSE STOCK SPLIT PROPOSAL Description of the REversE Split Shares combined at a 1-for-2 split ratio Implemented at discretion of Board at any time prior to the one-year anniversary of the Annual Meeting Fractional shares not issued - cash paid instead Reasons for the REVERSE SPLIT Trading price of Honeywell stock expected to decrease to reflect Honeywell Aerospace spin-off Reverse stock split would increase per-share price following spin-off to better align with peer companies of similar size/market cap Potentially improve marketability and trading interest in Honeywell stock Impact to Honeywell Shares Fewer shares outstanding, but ownership percentage and voting power unchanged (except fractional share cash-outs) Per-share metrics increase (e.g., EPS) due to lower share count Equity awards, dividends, and authorized shares adjusted proportionally 2026 Annual Meeting - Shareowner Engagement

Honeywell's Board Recommends 'AGAINST' Proposal 5 Proposal 5 SHAREOWNER PROPOSAL Shareholder Right to Act by Written Consent PROPOSAL: Requests the board of directors take the necessary steps to permit written consent by the shareowners entitled to cast the minimum number of votes that would be necessary to authorize an action at a shareowner meeting PROPONENT: John Chevedden HONEYWELL'S CONCERNS WITH THE PROPOSAL: Shareowner meetings are a more democratic means for shareowners to express their views Permitting shareowner action by written consent could lead to substantial confusion and disruption, with potentially multiple, even conflicting, written consents being solicited by multiple shareowner groups Shareowners holding 15% of our outstanding shares already have the right to call a special meeting (either in-person or in a virtual format) at any time Our shareowners have consistently expressed their comfort with our existing shareowner rights, including rejecting all prior proposals on this topic (Honeywell has received similar proposals six times between 2013 and 2025) The right to act by written consent is further unnecessary given Honeywell's other strong corporate governance practices 2026 Annual Meeting - Shareowner Engagement
