CARNEGIE RESEARCHERS EMPLOY INTERDISCIPLINARY EFFORTS TO INVESTIGATE HOW THE UNIVERSE WAS FORMED, HOW LIFE EVOLVED ON THIS PLANET, AND THE POTENTIAL FOR LIFE TO EXIST ELSEWHERE IN THE COSMOS. CARNEGIE OBSERVATIONAL AND THEORETICAL ASTRONOMERS COLLABORATE TO TRACE THE EVOLUTION OF THE UNIVERSE FROM THE SPARK OF THE BIG BANG THROUGH STAR AND GALAXY FORMATION; EXPLORE THE STRUCTURE OF THE UNIVERSE; AND PROBE THE MYSTERIES OF DARK MATTER, DARK ENERGY, AND THE EVER-ACCELERATING RATE AT WHICH THE UNIVERSE IS EXPANDING. UNLIKE MOST IN THEIR FIELD, CARNEGIE OBSERVATIONAL ASTRONOMERS DESIGN AND BUILD THEIR OWN INSTRUMENTS TO CAPTURE THE SECRETS OF SPACE. CARNEGIE OPERATES TELESCOPES AT LAS CAMPANAS OBSERVATORY IN CHILE, WHERE MUCH OF OUR ASTRONOMICAL RESEARCH IS CONDUCTED. WE ARE FOUNDING PARTNERS IN A CONSORTIUM THAT IS WORKING TO DESIGN, CONSTRUCT, AND OPERATE THE GIANT MAGELLAN TELESCOPE, ONE OF THE NEW CLASS OF EXTREMELY LARGE TELESCOPES, WHICH WILL BE AMONG THE WORLD'S LARGEST GROUND-BASED OPTICAL/INFRARED FACILITIES WHEN IT IS COMPLETED. CARNEGIE EARTH AND PLANETARY SCIENTISTS POSSESS EXPERTISE IN PETROLOGY, HIGH-PRESSURE AND HIGH-TEMPERATURE PHYSICS, AND NOVEL MATERIAL SYNTHESIS, AMONG OTHER CORE AREAS. SOME CARNEGIE SCIENTISTS ARE DISCOVERING PLANETS ORBITING DISTANT STARS; PROBING THE FORMATION AND EVOLUTION OF EARTH, THE MOON, AND OUR SOLAR SYSTEM; AND STUDYING THE CAUSES OF EARTHQUAKES, VOLCANOES, AND OTHER GEOLOGIC PHENOMENA. CARNEGIE BIOLOGISTS ARE EMPLOYING INNOVATIVE APPROACHES TO UNDERSTANDING THE INTERCONNECTED NATURE OF LIFE ON EARTH. WORKING ACROSS SCALES FROM GENOMES TO ECOSYSTEMS, CARNEGIE BIOLOGISTS ARE PROBING FUNDAMENTAL PLANET-SHAPING PROCESSES LIKE PHOTOSYNTHESIS AND GLOBAL NUTRIENT CYCLES, AS WELL AS THE MICROBIAL RELATIONSHIPS THAT UNDERPIN NEARLY EVERY ASPECT OF LIFE ON OUR PLANET. THEIR EFFORTS CAN INFORM AGRICULTURAL SUSTAINABILITY, ECOLOGICAL RESILIENCE, AND THE FIGHT AGAINST CLIMATE CHANGE, AS WELL AS INFORM THE SEARCH FOR BIOSIGNATURES ON DISTANT WORLDS. FORM 990, PART III, LINE 4B, PROGRAM SERVICE ACCOMPLISHMENTS: PROGRAM SERVICE ACTIVITY #2 EDUCATION - CARNEGIE, A NON-DEGREE GRANTING ENTITY, IS AN ADVANCED STUDY ORGANIZATION AT WHICH HIGHLY QUALIFIED GRADUATE SCIENTISTS ARE OFFERED POSTGRADUATE AND POSTDOCTORAL TRAINING FOR CAREERS IN EDUCATION AND RESEARCH. CARNEGIE'S POSTDOCTORAL SCIENTIFIC EDUCATION IS PRIMARILY CONDUCTED IN THE LABORATORY OR IN THE FIELD. THE POSTDOCTORAL CURRICULUM IS HEAVILY WEIGHTED TOWARD TRAINING CANDIDATES TO BE CAPABLE RESEARCHERS AND TEACHERS OF RESEARCH. THE FACULTY CONSISTS OF THE PROFESSIONAL STAFF OF CARNEGIE, ALL OF WHOM PURSUE THEIR OWN RESEARCH. CARNEGIE ALSO OFFERS CERTAIN TRAINING OPPORTUNITIES FOR PREDOCTORAL STUDENTS WHO MAY GO ON TO PURSUE ADVANCED DEGREES AT DEGREE-GRANTING INSTITUTIONS, AS WELL AS INTERNSHIP OPPORTUNITIES, BOTH THROUGH FORMAL PROGRAMS AND ON AN INDIVIDUAL, CASE-BY-CASE BASIS. CARNEGIE ALSO PARTNERS WITH LOCAL SCHOOLS AND SCHOOL DISTRICTS TO OFFER MORE INSTRUCTION ON ASTRONOMY AND PLANETARY SCIENCE, AND MAKES INFORMATION AVAILABLE CONCERNING CARNEGIE'S SCIENTIFIC RESEARCH FINDINGS TO THE GENERAL PUBLIC THROUGH LECTURES AND OTHER PROGRAMMING. FORM 990, PART VI, SECTION A, LINE 2 RELATIONSHIPS CHRISTOPHER STONE AND JOHN CRAWFORD: BUSINESS RELATIONSHIP FORM 990, PART VI, SECTION A, LINE 3 RANDY STRINGER RE-JOINED CARNEGIE SCIENCE IN APRIL 2025 AS THE INTERIM CHIEF FINANCIAL OFFICER. IN THIS ROLE, MR. STRINGER OVERSEES THE DAILY FINANCIAL OPERATIONS AS WELL AS PROVIDES EXPERTISE AROUND THE INSTITUTIONAL TRANSFORMATIONAL CHANGE THAT CARNEGIE IS UNDERGOING. MR. STRINGER REPORTS DIRECTLY TO CARNEGIE'S PRESIDENT, JOHN MULCHAEY. FORM 990, PART VI, SECTION B, LINE 11B FORM 990 REVIEW PROCESS CARNEGIE'S FINANCE DEPARTMENT, SENIOR STAFF AND ITS INDEPENDENT PAID PREPARER, GRANT THORNTON, WORK TOGETHER TO PREPARE AND REVIEW THE FORM 990. THE DRAFT FORM 990 IS THEN DISTRIBUTED TO MEMBERS OF THE AUDIT COMMITTEE OF THE BOARD OF TRUSTEES FOR REVIEW AND COMMENT. AFTER THE AUDIT COMMITTEE HAS REVIEWED THE RETURN AND ITS FEEDBACK HAS BEEN INCORPORATED, THE RETURN IS DISTRIBUTED TO ALL MEMBERS OF THE BOARD OF TRUSTEES FOR REVIEW AND COMMENT BEFORE IT IS FILED WITH THE IRS. TRUSTEES ARE ENCOURAGED TO CONTACT THE CHIEF OPERATING OFFICER OR DIRECTOR OF FINANCE WITH ANY QUESTIONS. FORM 990, PART VI, SECTION B, LINE 12C CONFLICT OF INTEREST POLICY CARNEGIE HAS ADOPTED CONFLICT OF INTEREST POLICIES THAT APPLY TO THE INSTITUTION'S TRUSTEES, CORPORATE OFFICERS, AND EMPLOYEES. THESE POLICIES REQUIRE EACH TRUSTEE TO COMPLETE ANNUALLY A FORM TO DISCLOSE ANY POTENTIAL CONFLICTS OF INTEREST. THE FORMS ARE COLLECTED BY THE CORPORATE SECRETARY, AND ANY DISCLOSURES ARE SUBSEQUENTLY PROVIDED TO THE BOARD OF TRUSTEES OR RELEVANT COMMITTEE OF THE BOARD FOR REVIEW AND APPROVAL. SIMILARLY, ALL EMPLOYEES OF CARNEGIE (INCLUDING CORPORATE OFFICERS) ARE REQUIRED, UPON HIRING AND ANNUALLY THEREAFTER, TO REPORT THEIR POTENTIAL CONFLICTS OF INTEREST. DEPARTMENT DIRECTORS REVIEW ALL POTENTIAL CONFLICTS IN THEIR DEPARTMENTS. THE PRESIDENT REVIEWS ALL POTENTIAL CONFLICTS FOR DEPARTMENT DIRECTORS. THE BOARD OF TRUSTEES REVIEWS ALL POTENTIAL CONFLICTS FOR THE CORPORATE OFFICERS. THROUGHOUT THE YEAR, EACH INDIVIDUAL SUBJECT TO THE CONFLICT OF INTEREST POLICIES IS REQUIRED TO UPDATE HIS/HER DISCLOSURE STATEMENT TO INCLUDE ANY INFORMATION REQUIRED TO BE DISCLOSED. THE SIGNED EMPLOYEE DISCLOSURE FORMS ARE KEPT IN THE EMPLOYEE'S PERSONNEL FILE. FORM 990, PART VI, SECTION B, LINE 15 PROCESS FOR DETERMINING EXECUTIVE COMPENSATION CARNEGIE ENGAGES AN INDEPENDENT COMPENSATION CONSULTING FIRM TO CONDUCT A COMPENSATION STUDY TO EVALUATE THE REASONABLENESS OF THE TOTAL PROPOSED COMPENSATION FOR THE ORGANIZATION'S "DISQUALIFIED PERSONS" UNDER TREAS. REG. 53.4958-3 WITHOUT REGARD TO WHETHER THE PERSON HAS BEEN ELECTED AN OFFICER. THE INDEPENDENT COMPENSATION STUDY FOCUSES ON THE COMPENSATION PAID TO FUNCTIONALLY COMPARABLE POSITIONS AT SIMILARLY- SITUATED ORGANIZATIONS AND ALSO CONSIDERS INDUSTRY COMPENSATION SURVEYS. THE COMPENSATION STUDY IS PROVIDED TO THE ORGANIZATION'S HUMAN RESOURCES AND COMPENSATION COMMITTEE, TOGETHER WITH A REASONED WRITTEN OPINION FROM THE COMPENSATION CONSULTANT THAT THE PROPOSED COMPENSATION ARRANGEMENTS FOR THE DISQUALIFIED PERSONS ARE "REASONABLE" WITHIN THE MEANING OF TREAS. REG. 53.4958-4(B)(1)(II)(A). THE HUMAN RESOURCES AND COMPENSATION COMMITTEE SETS COMPENSATION FOR EACH DISQUALIFIED PERSON AND MAKES A RECOMMENDATION TO THE FULL BOARD OF TRUSTEES WITH RESPECT TO COMPENSATION FOR THE PRESIDENT. THE FULL BOARD THEN REVIEWS THE COMPENSATION STUDY AND OPINION FOR THE PRESIDENT TOGETHER WITH THE RECOMMENDATION OF THE HUMAN RESOURCES AND COMPENSATION COMMITTEE AND MAKES A DECISION WITH RESPECT TO THE PRESIDENT'S COMPENSATION. THE HUMAN RESOURCES AND COMPENSATION COMMITTEE AND BOARD RELY ON THE COMPENSATION CONSULTANT'S OPINION AND COMPENSATION STUDY TO GUIDE ITS REVIEW, DELIBERATION, AND APPROVAL OF THE PROPOSED COMPENSATION ARRANGEMENTS, AND ITS DECISIONS REGARDING COMPENSATION (INCLUDING THE BASES FOR THESE DECISIONS) ARE DOCUMENTED IN THE MEETING MINUTES. THE HUMAN RESOURCES AND COMPENSATION COMMITTEE AND TRUSTEES WHO VOTE ON COMPENSATION FOR DISQUALIFIED PERSONS AND THE PRESIDENT DO NOT HAVE A CONFLICT OF INTEREST WITH REGARD TO THESE COMPENSATION ARRANGEMENTS.
