Inclusion Criteria: 1. Patients with histologically (core biopsy) or cytologically (e.g., bronchoscopy-guided biopsy) confirmed non-small-cell lung cancer (NSCLC) eligible for anatomic resection, with the following specifications: * Clinical stages I B, II or selected stage III A (T3 N1, T4 with satellite nodule in the same lung N0/N1, selected T1a-T2b N2 cases considered suitable for primary surgical approach by the multidisciplinary tumor board) according to UICC 8th edition * Confirmation of an oncogenic EGFR mutation (EGFR p.L858R, EGFR exon 19 in-frame deletion, EGFR exon 20 in-frame insertions, EGFR p.S768I, EGFR p.L861Q, EGFR p.G719x - additional EGFR mutations with clinically validated oncogenicity and susceptibility to amivantamab may be eligible following discussion and approval by the coordinating investigator in his capacity as sponsor representative) by validated assaytechnology (e.g., diagnostic NGS or PCR-based genotyping, adhering to quality standards defined by the nNGM Lung Cancer biomarker standard operating procedure (version 007 or higher) in Germany, or equivalent in Belgium and the Netherlands) in a pretreatment biopsy (primary tumor or lymph node metastasis) 2. Males and females, ages \>= 18 years, inclusive * A participant of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin \[hCG\]) within 24 hours prior to the start of study treatment and must agree to further serum or urine pregnancy testing during the study. * A participant must be (as defined in Appendix IV: Contraceptive Guidance and Collection of Pregnancy Information) either of the following: * Not of childbearing potential * Of child-bearing potential and practicing true abstinence during the entire period of the study, including up to 6 months after the last dose of study treatment is given * Of childbearing potential and practicing 2 methods of contraception, including 1 highly effective user independent method and a second method (examples of highly effective methods of contraception are located in Appendix IV: Contraceptive Guidance and Collection of Pregnancy Information).Participant must agree to continue contraception throughout the study and through 6 months after the last dose of study treatment. * Note: If the childbearing potential changes after start of the study (e.g., participant of childbearing potential who is not heterosexually active becomes active, premenarchal participant experiences menarche) the participant must begin birth control, as described above * A participant must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for 6 months after receiving the last dose of study treatment. * A participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person during the study and for 6 months after receiving the last dose of study treatment. A participant who is sexually active with a partner of childbearing potential must agree to use a condom with spermicidal foam/gel/film/cream/suppository and their partner must also be practicing a highly effective method of contraception (i.e., established use of oral, injected, or implanted hormonal methods of contraception; placement of an intrauterine device \[IUD\] or intrauterine hormone-releasing system \[IUS\]). If the participant is vasectomized, they must still use a condom (with or without spermicide) for prevention of passage of exposure through ejaculation, but their partner is not required to use contraception. * A participant must agree not to donate sperm for the purpose of reproduction during the study and for a minimum of 6 months after receiving the last dose of study treatment. * Participant must be willing and able to adhere to the lifestyle restrictions specified in this protocol. 3.
