CH2M HILL CORP.

Shareholders of CH2M HILL CORP.

Colorado publishes no shareholder register. For a foreign profit corporation the Colorado Secretary of State records the entity, its principal address, its entity type and jurisdiction of formation, and its registered agent — not its shareholders or members. No shareholder information exists in the Colorado record for entity ID 19871555433. Absence of a shareholder filing is a feature of Colorado’s disclosure regime and is not evidence that the company has no shareholders.

One item of SEC material bears on ownership. Exhibit 21 to the Form S-1 filed with the SEC on 15 March 1999 by CH2M HILL Companies, Ltd. lists “CH2M Hill Corp., an Oregon corporation” among that company’s subsidiaries. The name and the state of formation match this Colorado record, but the exhibit does not cite a Colorado entity ID, so the identification rests on name and formation state alone. The exhibit states no ownership percentage, so no holding level can be attributed to it. This is group-level material describing the CH2M HILL Companies, Ltd. group as at March 1999.

No SEC filing reviewed establishes any later change of ownership in an Oregon corporation of this name. The 2017 acquisition of CH2M HILL Companies, Ltd. by Jacobs Engineering Group Inc. changed the ownership of that Delaware parent, not of this registration; see the group structure section.

Data availability

No shareholder, member or ownership-percentage data is published for this registration by the Colorado Secretary of State. The single ownership-relevant primary document located is the 1999 SEC subsidiary exhibit cited below, which gives no percentages.

Directors and officers of CH2M HILL CORP.

The Colorado Secretary of State names no individual in connection with entity ID 19871555433. The record carries one party only, under Colorado’s own label agent organization name:

• National Registered Agents, Inc — registered agent. Address of record: 7700 E Arapahoe Rd Ste 220, Centennial, CO 80112-1268, United States. This is a corporate registered-agent provider, not a natural person. Nationality: Not disclosed.

A Colorado registered agent is the party designated to receive service of process and official notices. The role carries no management authority and does not make the agent a director, officer or owner of the entity.

No director, officer or principal is recorded against this registration. The register’s transaction history for 1984 to 2016 contains applications for authority, periodic reports, registered-agent amendments and the 2003 withdrawal; none of these filings records an individual’s name.

The registration was withdrawn on 24 April 2003, so no person can be identified as a current officer of it. The most recent transaction on the record, a “Statement of Change Changing the Registered Agent Information” dated 16 September 2016, was a bulk filing that the register notes as listing all affected entities; it post-dates the withdrawal by more than thirteen years and is administrative rather than evidence of continuing activity.

Data availability

Colorado publishes the registered agent for every registered entity, and a principal office address, but does not require or publish a director or officer list for a foreign profit corporation. No dates of birth, nationalities or residential addresses are published. Nationality is shown as not disclosed because the register does not state it; it has not been inferred.

Group structure of CH2M HILL CORP.

The Colorado Secretary of State records no parent, subsidiary, branch or other ownership linkage for entity ID 19871555433. Colorado does not publish group structure.

Documented group link (1999). Exhibit 21 to the Form S-1 filed with the SEC on 15 March 1999 by CH2M HILL Companies, Ltd. lists six subsidiaries, one of which is “CH2M Hill Corp., an Oregon corporation”. Relationship type: subsidiary of CH2M HILL Companies, Ltd. The exhibit states no ownership percentage, so no wholly-owned holding may be assumed. The exhibit does not cite a Colorado entity ID; the identification of this registration rests on the matching name and matching state of formation (Oregon). This is group-level material and describes the position as at March 1999.

The parent has its own separate Colorado registration. CH2M HILL COMPANIES, LTD. is registered in Colorado under entity ID 19871550800 as a foreign profit corporation formed in Delaware, status Good Standing. It is a distinct registration from 19871555433 and its filings should not be read against this record.

The Jacobs acquisition concerns the parent, not this registration. The Current Report on Form 8-K filed with the SEC on 18 December 2017 by CH2M HILL Companies, Ltd. (a Delaware corporation, Commission File Number 000-27261) reports that on 15 December 2017, under an Agreement and Plan of Merger dated 1 August 2017, CH2M HILL Companies, Ltd. merged with and into Basketball Merger Sub Inc., a wholly-owned subsidiary of Jacobs Engineering Group Inc., with CH2M HILL Companies, Ltd. surviving the merger and becoming a direct, wholly-owned subsidiary of Jacobs Engineering Group Inc. The same company filed a Form 15-12G on 18 December 2017 terminating the registration of its common stock under section 12(g).

That transaction is an acquisition of the Delaware parent. Exhibit 21.1 to the last annual report filed by CH2M HILL Companies, Ltd. before the merger — the Form 10-K for the fiscal year ended 30 December 2016, filed 7 March 2017 — does not list an Oregon corporation named CH2M Hill Corp. among the group’s subsidiaries. No filing reviewed ties entity 19871555433 to the Jacobs transaction, and the Colorado registration had already been withdrawn in April 2003, more than fourteen years before the merger completed.

Data availability

No group, parent or subsidiary data is published for this registration by the Colorado Secretary of State. The group relationships stated above come from SEC filings of CH2M HILL Companies, Ltd. and are attributed to that company and to the years given. The last documented group link for an Oregon corporation of this name is March 1999; whether the entity existed after the 2003 Colorado withdrawal could not be established from Colorado’s record, and the Oregon Secretary of State’s register was not reachable.
