Exhibit 99.5

FORM OF LETTER

TEJON RANCH CO.

Subscription Rights to Purchase Shares of Common Stock

Offered Pursuant to Subscription Rights

Distributed to Stockholders of

Tejon Ranch Co.

October [●], 2017

To Our Clients:

Enclosed for your consideration are a prospectus, dated October 4, 2017 (the “Prospectus”), and the “Instructions as to Use of Tejon Ranch Co. Rights Certificates” relating to the offering (the “Rights Offering”) by Tejon Ranch Co. (“Tejon”) of shares of Common Stock (as defined below) pursuant to transferable subscription rights (the “Rights”) distributed to all holders of record of shares of the Company’s common stock, par value $0.50 per share (the “Common Stock”), at 5:00 p.m., New York time, on October 4, 2017 (the “Record Date”). The Rights and Common Stock are described in the Prospectus.

In the Rights Offering, Tejon is offering an aggregate of 4,173,067 shares of Common Stock, as described in the Prospectus.

The Rights will expire, if not exercised prior to 5:00 p.m., New York time, on October 27, 2017, unless extended (the “Expiration Time”).

As described in the accompanying Prospectus, you will receive one Right for each share of Common Stock owned at 5:00 p.m., New York time, on the Record Date. Each Right will allow you to subscribe for 0.20 shares of Common Stock (the “Basic Subscription Privilege”) at the cash price of $18.00 per full share (the “Subscription Price”). For example, if you owned 100 shares of Common Stock as of 5:00 p.m., New York City time, on the Record Date, you would receive 100 Rights and would have the right to purchase 20 shares of Common Stock (rounded down, if applicable, to the nearest whole share, with the total subscription payment being adjusted accordingly, as discussed below) for the Subscription Price.

In the event that you purchase all of the shares of common stock available to you pursuant to your Basic Subscription Privilege, you may also exercise an over-subscription privilege (the “Over-Subscription Privilege”) to purchase a portion of any shares of Common Stock that are not purchased by stockholders through the exercise of their Basic Subscription Privileges (the “Unsubscribed Shares”), subject to the availability and pro rata allocation of the Unsubscribed Shares among all persons exercising this Over-Subscription Privilege. If there are not enough Unsubscribed Shares to honor all Over-Subscription Privilege requests, Tejon may, in its discretion, issue up to an additional 833,333 shares (the “Over-Allotment Shares”). To the extent the Unsubscribed Shares, including any Over-Allotment Shares, are not sufficient to satisfy all of the properly exercised Over-Subscription Privileges, then the Unsubscribed Shares will be prorated among those who properly exercised Over-Subscription Privilege based on the number of shares each person subscribed for under the Basic Subscription Privilege. If this pro rata allocation results in any person receiving a greater number of Unsubscribed Shares than the person subscribed for pursuant to the exercise of the Over-Subscription Privilege, then such person will be allocated only that number of Unsubscribed Shares for which the person oversubscribed, and the remaining Unsubscribed Shares will be allocated among all other persons exercising the Over-Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Unsubscribed Shares have been allocated or all Over-Subscription Privileges have been fulfilled, whichever occurs earlier.

You will be required to submit payment in full for all the shares you wish to buy with your Over-Subscription Privilege. Because we will not know the total number of Unsubscribed Shares prior to the Expiration Date, if you wish to maximize the number of shares you may purchase pursuant to your Over-

Subscription Privilege, you will need to deliver payment in an amount equal to the aggregate Subscription Price for the maximum number of shares of Common Stock available to you, assuming that no stockholder other than you has purchased any shares of Common Stock pursuant to the Basic Subscription Privilege and Over-Subscription Privilege. Tejon will eliminate fractional shares of Common Stock resulting from the exercise of the Over-Subscription Privilege by rounding down to the nearest whole share, with the total subscription payment being adjusted accordingly. Any excess subscription payments received by the Subscription Agent will be returned, without interest, as soon as practicable.

Tejon can provide no assurances that you will actually be entitled to purchase the number of shares of Common Stock issuable upon the exercise of your Over-Subscription Privilege in full at the expiration of the Rights Offering. Tejon will not be able to satisfy your exercise of the Over-Subscription Privilege if all of our stockholders exercise their Basic Subscription Privileges in full, and we will only honor an Over-Subscription Privilege to the extent sufficient shares of Common Stock are available following the exercise of subscription rights under the Basic Subscription Privileges. However, if there are not enough Unsubscribed Shares to honor all Over-Subscription Privilege requests, Tejon may, in its discretion, issue the Over-Allotment Shares.

To the extent the aggregate Subscription Price of the maximum number of Unsubscribed Shares available to you pursuant to the Over-Subscription Privilege is less than the amount you actually paid in connection with the exercise of the Over-Subscription Privilege, you will be allocated only the number of Unsubscribed Shares available to you as soon as practicable after the Expiration Time, and your excess subscription payment received by the Subscription Agent will be returned, without interest, as soon as practicable. To the extent the amount you actually paid in connection with the exercise of the Over-Subscription Privilege is less than the aggregate Subscription Price of the maximum number of Unsubscribed Shares available to you pursuant to the Over-Subscription Privilege; you will be allocated the number of Unsubscribed Shares for which you actually paid in connection with the Over-Subscription Privilege. See “The Rights Offering — Over-Subscription and Over-Allotment Privilege.”

The Rights are evidenced by a transferable Rights certificate (the “Rights Certificate”) and will cease to have any value at the Expiration Time.
