Desc	MEDICAL RESEARCH ORGANIZATION ACTIVITIES THE HHMI INVESTIGATOR PROGRAM THE HOWARD HUGHES MEDICAL INSTITUTE'S APPROACH TO BIOMEDICAL RESEARCH CAN BE SUMMARIZED IN THREE WORDS: PEOPLE, NOT PROJECTS. THIS COMMITMENT IS REFLECTED IN THE HHMI INVESTIGATOR PROGRAM. RATHER THAN AWARDING RESEARCH GRANTS, THIS PROGRAM EMPLOYS SCIENTISTS,PROVIDING THEM WITH LONG-TERM, FLEXIBLE FUNDING THAT THEY MAY USE TO PURSUE THEIR SCIENTIFIC INTERESTS. HHMI BELIEVES THAT SCIENTISTS OF EXCEPTIONAL TALENT AND IMAGINATION WILL MAKE FUNDAMENTAL DISCOVERIES OF LASTING SCIENTIFIC VALUE ANDTHATBENEFITHUMAN HEALTHIF THEY ARE GIVEN THE RESOURCES, TIME, AND FREEDOM TO PURSUE CHALLENGING QUESTIONS. HHMI INVESTIGATORS RECEIVE A SEVEN-YEAR APPOINTMENT, WHICH ISRENEWABLEPENDING FAVORABLE SCIENTIFIC REVIEW. AMONG THE MORE THAN265 CURRENT HHMI INVESTIGATORS, 16 ARENOBEL LAUREATES ANDNEARLY150AREMEMBERS OF THE NATIONAL ACADEMY OF SCIENCES. HHMI INVESTIGATORS DIRECT HHMI RESEARCH LABORATORIESLOCATEDON THE CAMPUSES OFMORE THAN 55HOSPITALS,UNIVERSITIES,AND OTHER RESEARCHINSTITUTIONSTHROUGHOUT THE UNITED STATES. SINCE THE EARLY 1990S, INVESTIGATORS HAVE BEEN SELECTED THROUGH RIGOROUS NATIONAL COMPETITIONS. THE INSTITUTESOLICITSAPPLICATIONS DIRECTLY FROM SCIENTISTS AT RESEARCH INSTITUTIONS IN THE UNITED STATES, WITH THE AIM OFIDENTIFYINGTHOSE WHO HAVE THE POTENTIAL TO MAKE SIGNIFICANT CONTRIBUTIONS TO SCIENCE. HHMI EMPLOYS AN OPEN APPLICATION PROCESS TO ENSURE THAT IT SELECTS ITS RESEARCHERS FROM A BROAD AND DEEP POOL OF SCIENTIFIC TALENT. JANELIA RESEARCH CAMPUS HHMI'S JANELIA RESEARCH CAMPUS IN ASHBURN, VIRGINIA, INNOVATES RESEARCH PRACTICES, TOOLS, AND TECHNOLOGIES TO SOLVE BIOLOGY'S DEEPEST MYSTERIES. AT JANELIA, INTEGRATED TEAMS OF LAB SCIENTISTS AND TOOL-BUILDERS PURSUE A SMALL NUMBER OF KEY SCIENTIFIC QUESTIONS WITH THE POTENTIAL FOR TRANSFORMATIVE IMPACT. TO DRIVE SCIENCE, THESE DISCOVERIES ARE SHARED OPENLY WITH THE SCIENTIFIC COMMUNITY. IN FY24, HHMI ANNOUNCED AI@HHMI, A 10-YEAR, $500 MILLION INVESTMENT TO SUPPORT AI-DRIVEN PROJECTS AND EMBED AI SYSTEMS THROUGHOUT EVERY STAGE OF THE SCIENTIFIC PROCESS. IN FY25, THE INSTITUTE ANNOUNCED SIX AMBITIOUS AI PROJECTS SPEARHEADED BY BOTH HHMI INVESTIGATORS AND JANELIA GROUP LEADERS. IN THE CURRENT FISCAL YEAR, THERE WERE27GROUP LEADERS,16SENIOR GROUP LEADERS, AND8JANELIA SCHOLARS AT JANELIA, IN ADDITION TO GRADUATE STUDENTS, POSTDOCS, AND VISITING SCIENTISTS. JANELIA ALSO HOSTS A VIBRANT SCIENTIFIC CONFERENCE PROGRAM, WHICH BRINGS MANY SCIENTISTS TO ITS CAMPUS EACH YEAR FOR EDUCATIONAL MEETINGS. THE FREEMAN HRABOWSKI SCHOLARS PROGRAM THE FREEMAN HRABOWSKI SCHOLARS PROGRAM SUPPORTS OUTSTANDING EARLY CAREER BASIC RESEARCHERS WHO HAVE STRONG POTENTIAL TO BECOME LEADERS IN THEIR FIELDS. SCHOLARS PRIORITIZE SCIENTIFIC EXCELLENCE IN THEIR OWN RESEARCH WHILE CREATING LAB CLIMATES IN WHICH EVERYONE CAN THRIVE. LIKE HHMI INVESTIGATORS, SCHOLARS ARE EMPLOYEES OF THE INSTITUTEBASED AT HOSPITALS, UNIVERSITIES, AND OTHER RESEARCH INSTITUTES IN THE UNITED STATES,ANDAREPROVIDED WITH LONG-TERM, FLEXIBLE FUNDING TO PURSUE THEIR BOLDEST IDEAS. EACH SCHOLAR IS APPOINTED FOR UP TO TWO FIVE-YEAR TERMS. INTHE SUMMER OF 2025, HHMI ANNOUNCED ITS SECOND COHORT OF FREEMAN HRABOWSKI SCHOLARS: 30 EXCEPTIONAL SCIENTISTS FROM 23 U.S. RESEARCH INSTITUTIONS. ONCE APPOINTED, THEY WILL JOIN THE 31 INAUGURAL FREEMAN HRABOWSKI SCHOLARS.THE PROGRAM IS NAMED AFTER FREEMAN A. HRABOWSKI III, PRESIDENT EMERITUS OF THE UNIVERSITY OF MARYLAND, BALTIMORE COUNTY.

Schedule J, Part I, Line 1a First-class or charter travel	UNDER HHMI POLICIES, HHMI REIMBURSES ITS TRUSTEES FOR THE REASONABLE COST OF AIRFARE ONE CLASS ABOVE ECONOMY/PREMIUM ECONOMY FOR DOMESTIC AND INTERNATIONAL FLIGHTS, AND ITS EMPLOYEES (INCLUDING ITS OFFICERS) FOR THE REASONABLE COST OF AIRFARE AT ONE CLASS ABOVE ECONOMY/PREMIUM ECONOMY FOR INTERNATIONAL TRIPS EXCEEDING SIX HOURS FLYING TIME AND RED-EYE FLIGHTS. IF A PARTICULAR AIRCRAFT DOES NOT HAVE A BUSINESS CLASS SECTION, ONE CLASS ABOVE ECONOMY/PREMIUM ECONOMY MAY BE FIRST CLASS. SUCH TRAVEL REIMBURSEMENTS ARE EXCLUDED FROM TAXABLE COMPENSATION IN ACCORDANCE WITH HHMI'S ACCOUNTABLE PLAN. DURING FISCAL YEAR 2025, 3 OFFICERS, 6 TRUSTEES, AND 2 HIGHEST COMPENSATED EMPLOYEES FLEW FIRST CLASS.
Schedule J, Part I, Line 1a Housing allowance or residence for personal use	HHMI'S PRESIDENT RESIDES IN AN HHMI-OWNED HOUSE ON THE HEADQUARTERS CAMPUS AND IS REQUIRED TO LIVE IN THIS RESIDENCE AS A CONDITION OF EMPLOYMENT. BECAUSE HHMI'S PRESIDENT IS ALSO REQUIRED TO SPEND TIME AT HHMI'S JANELIA CAMPUS, WHERE SHE RUNS A RESEARCH LABORATORY, ATTENDS MEETINGS, AND PARTICIPATES IN CONFERENCES, HHMI MAKES AN APARTMENT AVAILABLE TO HER AT THAT LOCATION. ADDITIONALLY, HHMI'S VICE PRESIDENT AND EXECUTIVE DIRECTOR, JANELIA RESEARCH CAMPUS, IS REQUIRED AS A CONDITION OF EMPLOYMENT TO RESIDE ON THE JANELIA CAMPUS IN HOUSING BUILT FOR THAT PURPOSE.
Schedule J, Part I, Line 4b Supplemental nonqualified retirement plan	THE INSTITUTE HAS ESTABLISHED A NONQUALIFIED DEFERRED COMPENSATION PLAN FOR ITS PRESIDENT AND ITS VP & GENERAL COUNSEL & SECRETARY. THE DEFERRED COMPENSATION PLANS HAVE BOTH A PERFORMANCE PERIOD AS WELL AS PERFORMANCE GOALS. THESE AMOUNTS ARE NOT YET VESTED AND ARE SUBJECT TO SUBSTANTIAL RISK OF FORFEITURE.
Schedule J, Part I, Line 7 Non-fixed payments	HHMI HAS AN INCENTIVE COMPENSATION PROGRAM FOR ITS INVESTMENT STAFF WHICH PROVIDES AN ANNUAL INCENTIVE AWARD THAT INCLUDES A QUANTITATIVE COMPONENT BASED ON PERFORMANCE OF HHMI'S PORTFOLIO AGAINST MARKET BENCHMARKS AND A DISCRETIONARY QUALITATIVE COMPONENT BASED ON INDIVIDUAL PERFORMANCE, INCLUDING ATTRIBUTES NOT DIRECTLY TIED TO PORTFOLIO PERFORMANCE. HHMI'S TRUSTEES APPROVED RETENTION PAYMENTS FOR CALENDAR 2024 IN LIEU OF PAYMENTS UNDER THE INCENTIVE COMPENSATION PROGRAM. EACH YEAR, THESE PAYMENTS ARE APPROVED BY THE TRUSTEES IN RELIANCE ON COMPARABILITY DATA AND A REASONABLENESS OPINION PROVIDED BY AN INDEPENDENT COMPENSATION CONSULTANT. HHMI ALSO MAKES ONE-TIME PAYMENTS TO SOME OF ITS OTHER EMPLOYEES, INCLUDING BUT NOT LIMITED TO OFFICERS, IN RECOGNITION OF EXCEPTIONAL PERFORMANCE.
Schedule J, Part I, Line 8 Payments on contract that is subject to the initial contract exception	WHEN RECRUITING INDIVIDUALS FOR HIGH-LEVEL POSITIONS, HHMI TYPICALLY ENTERS INTO INITIAL CONTRACTS. HHMI HAS ENTERED INTO INITIAL CONTRACTS WITH A NUMBER OF VICE PRESIDENTS. HHMI'S STANDARD PRACTICE IS TO HAVE INDEPENDENT COMPENSATION CONSULTANTS REGULARLY REVIEW AND CONFIRM THE REASONABLENESS OF COMPENSATION OF HHMI'S OFFICERS AND KEY EMPLOYEES, REGARDLESS OF WHETHER THE INITIAL CONTRACT EXCEPTION APPLIES.

Form 990, Part VI, Line 11b Review of form 990 by governing body	THE HOWARD HUGHES MEDICAL INSTITUTE'S FORM 990 IS INITIALLY PREPARED BY ITS TAX COMPLIANCE DEPARTMENT, IN COORDINATION WITH OTHER HHMI DEPARTMENTS AS NEEDED. THE DRAFT RETURN IS REVIEWED BY SENIOR MANAGEMENT OF HHMI AND BY ATTORNEYS IN HHMI'S OFFICE OF THE GENERAL COUNSEL. FOLLOWING THESE REVIEWS AND THE RESOLUTION OF ANY QUESTIONS THAT HAVE BEEN RAISED, THE DRAFT RETURN IS REVIEWED BY HHMI'S OUTSIDE TAX PREPARER. FINALLY, A COPY OF THE RETURN IS PROVIDED TO THE MEMBERS OF HHMI'S BOARD OF TRUSTEES SO THAT THEY HAVE AN OPPORTUNITY TO REVIEW AND COMMENT ON THE RETURN BEFORE IT IS FILED.
Form 990, Part VI, Line 12c Conflict of interest policy	IN ADDITION TO HHMI'S CODE OF CONDUCT, WHICH ADDRESSES CONFLICTS OF INTEREST AND APPLIES TO ALL HHMI EMPLOYEES, OFFICERS, TRUSTEES, AND ADVISORS, HHMI HAS SPECIFIC CONFLICT OF INTEREST POLICIES FOR DIFFERENT CATEGORIES OF PERSONNEL. UNDER THE HHMI POLICIES THAT APPLY TO TRUSTEES, OFFICERS, AND KEY EMPLOYEES, THESE INDIVIDUALS MUST DISCLOSE ANNUALLY INTERESTS THAT COULD GIVE RISE TO CONFLICTS OF INTEREST, AND MUST CERTIFY ANNUALLY THEIR COMPLIANCE WITH THE CONFLICT OF INTEREST POLICY THAT APPLIES TO THEM. ANNUAL DISCLOSURES AND CERTIFICATIONS ARE REVIEWED BY HHMI'S OFFICE OF THE GENERAL COUNSEL, AND BY OTHER HHMI MANAGERS AS NEEDED. THE CONFLICT OF INTEREST POLICY COVERING HHMI'S TRUSTEES ALSO REQUIRES EACH TRUSTEE TO DISCLOSE TO THE OTHER TRUSTEES ANY ACTUAL OR APPARENT CONFLICT OF INTEREST WITH RESPECT TO A PROPOSED HHMI TRANSACTION. IF THE OTHER TRUSTEES DECIDE THAT THERE IS ONLY THE APPEARANCE OF A CONFLICT OF INTEREST, AND THAT IT COULD NOT REASONABLY BE CONSIDERED TO AFFECT THE INDEPENDENT, UNBIASED JUDGMENT OF THE DISCLOSING TRUSTEE WITH RESPECT TO THE TRANSACTION AT ISSUE, NO FURTHER ACTION IS REQUIRED TO ADDRESS THE APPARENT CONFLICT. IN ALL OTHER CASES, INCLUDING ALL ACTUAL CONFLICTS OF INTEREST, THE DISCLOSING TRUSTEE IS NOT PERMITTED TO PARTICIPATE IN THE DELIBERATION OR DECISION REGARDING THE TRANSACTION UNDER CONSIDERATION, AND MUST LEAVE THE ROOM DURING THE DELIBERATION AND VOTE. THE CONFLICT OF INTEREST POLICIES COVERING HHMI'S OFFICERS AND KEY EMPLOYEES REQUIRE EACH COVERED INDIVIDUAL TO OBTAIN SUPERVISORY APPROVAL UP TO THE LEVEL OF HHMI'S PRESIDENT BEFORE ENTERING INTO AN AFFILIATION WITH OR ACQUIRING AN INTEREST OF 1% OR MORE IN ANY ENTITY THAT IS OR MAY BECOME A RECIPIENT OF HHMI FUNDS. HHMI'S PRESIDENT, IN CONSULTATION WITH HHMI'S GENERAL COUNSEL, MAY PERMIT THE AFFILIATION OR INTEREST IF IT WOULD NOT INTERFERE WITH THE COVERED INDIVIDUAL'S PERFORMANCE OF HIS OR HER HHMI RESPONSIBILITIES, WOULD NOT CREATE THE APPEARANCE OF A CONFLICT OF INTEREST, AND WOULD BE CONSISTENT WITH SOUND BUSINESS JUDGMENT. HHMI'S PRESIDENT MAY SET CONDITIONS ON APPROVAL, FOR EXAMPLE THAT THERE BE NO REMUNERATION TO THE COVERED INDIVIDUAL. PROPOSED AFFILIATIONS AND INTERESTS OF 1% OR MORE OF HHMI'S PRESIDENT ARE SUBJECT TO THE APPROVAL OF THE CHAIR OF THE TRUSTEES.
Form 990, Part VI, Line 15a Process to establish compensation of top management official	THE COMPENSATION FOR HHMI'S PRESIDENT, OTHER OFFICERS, AND KEY EMPLOYEES IS SET USING THE FOLLOWING PROCEDURES: EVERY OTHER YEAR, THE AUDIT & COMPENSATION COMMITTEE OF HHMI'S BOARD OF TRUSTEES ENGAGES ONE OR MORE INDEPENDENT COMPENSATION CONSULTANTS TO CONDUCT A STUDY OF COMPARABLE MARKET DATA. THE STUDY INCLUDES DATA FOR HHMI'S PRESIDENT, OTHER OFFICERS, AND KEY EMPLOYEES. THE INDEPENDENT COMPENSATION CONSULTANTS ALSO PROVIDE AN OPINION REGARDING THE REASONABLENESS OF THE COMPENSATION ARRANGEMENTS FOR THE POSITIONS INCLUDED IN THE STUDY. THE STUDY INCLUDES COMPARABLE MARKET DATA FOR ALL COMPONENTS OF COMPENSATION FOR EACH PERSON COVERED BY THE STUDY, INCLUDING BASE SALARY, INCENTIVE COMPENSATION (IF ANY), AND BENEFITS. THE BOARD OF TRUSTEES RELIES ON THE MARKET DATA AND OPINION PROVIDED BY THE COMPENSATION CONSULTANT IN MAKING COMPENSATION DECISIONS FOR HHMI'S PRESIDENT, OTHER OFFICERS, AND KEY EMPLOYEES. THE DECISION IS MADE BY INDEPENDENT TRUSTEES. ANY TRUSTEE WHO HAS A CONFLICT OF INTEREST WITH RESPECT TO A SPECIFIC OFFICER OR KEY EMPLOYEE MUST RECUSE HIMSELF OR HERSELF FROM THE DECISION ON THAT PERSON'S COMPENSATION AND LEAVE THE MEETING ROOM DURING THE DEBATE AND VOTE ON IT. IN THE ALTERNATE YEARS WHEN A STUDY IS NOT DONE, THE TRUSTEES CONFIRM WITH THE INDEPENDENT COMPENSATION CONSULTANTS THAT THE RANGE OF ANY PROPOSED MERIT INCREASES FOR HHMI EMPLOYEES, INCLUDING SENIOR MANAGEMENT, IS REASONABLE COMPARED WITH THE GENERALLY PREVAILING COMPENSATION INCREASES IN THE MARKET OVER THE PAST YEAR. THE BOARD OF TRUSTEES RELIES ON THIS ADVICE IN MAKING COMPENSATION DECISIONS FOR HHMI'S PRESIDENT, OTHER OFFICERS AND KEY EMPLOYEES. RECUSAL PROCEDURES ARE THE SAME AS IN THE YEARS WHEN A STUDY IS DONE. IN EACH YEAR, MINUTES OF THE DISCUSSIONS AND DECISIONS REGARDING COMPENSATION ARE PREPARED AFTER EACH MEETING AND ARE SUBMITTED FOR APPROVAL AT THE NEXT MEETING. APPROVED MINUTES ARE KEPT IN HHMI'S RECORDS. ALL MINUTES INCLUDE THE DATE OF THE MEETING, IDENTIFY THOSE TRUSTEES WHO ATTENDED AND VOTED ON THE COMPENSATION ARRANGEMENTS, AND NOTE ANY RECUSALS OF TRUSTEES WITH A CONFLICT OF INTEREST. THE COMPARABILITY STUDIES AND OPINIONS RELIED ON AT THE MEETING ARE REFERENCED IN THE MINUTES, AND COPIES OF THESE MATERIALS ARE ALSO KEPT IN HHMI'S RECORDS. HHMI'S BOARD OF TRUSTEES FOLLOWED THIS PROCESS IN AUGUST 2025 IN DETERMINING COMPENSATION FOR THE FOLLOWING POSITIONS FOR FISCAL YEAR 2026: PRESIDENT, OTHER OFFICERS, AND INVESTMENT DEPARTMENT MANAGING DIRECTORS.
