SECTION 1 - CONFLICT MINERALS DISCLOSURE

ITEM 1.01 CONFLICT MINERALS DISCLOSURE AND REPORT

(a) Technical Communications Corporation (“TCC”) has determined that during calendar year 2016 certain of its products were likely to contain “conflict minerals,” as such term is defined in Rule 13p-1 promulgated under the Securities Exchange Act of 1934, as amended, necessary to the functionality or production of such products. In 2016, TCC contracted for the manufacture of products likely containing conflict minerals but did not directly manufacture any such products.

(b) TCC conducted a reasonable country of origin inquiry for calendar year 2016 regarding conflict minerals utilized in its products. That reasonable country of origin inquiry was designed to determine whether those conflict minerals likely present in TCC products originated in the Democratic Republic of the Congo or an adjoining country (together, the “Covered Countries”) or arose from recycled or scrap sources. That reasonable country of origin inquiry revealed that necessary conflict minerals did not likely arise from scrap or recycled sources; TCC was unable to determine whether they originated in any of the Covered Countries.

(c) TCC exercised due diligence regarding the source and chain of custody of its conflict minerals through a reasonably designed due diligence framework, as more particularly described in the Conflict Minerals Report filed as Exhibit 1.01. TCC is unable, after exercising due diligence, to determine whether the supplier parts utilized in its products contain conflict minerals that finance or benefit, directly or indirectly, armed groups in the Covered Countries.
